I will fan and medal
can you please help mw with the steps
Part A: Factor 3x^2y^2 − 2xy^2 − 8y^2. Show your work. (4 points)
Part B: Factor x^2 + 10x + 25. Show your work. (3 points)
Part C: Factor x^2 − 36. Show your work. (3 points)
these are my answers
part a: y^2=(3x+4)(x2)
part b: (x+5)(x+5)
part c: (x+6)(x6)

Best ResponseYou've already chosen the best response.0so....have you done any factoring? have you covered factoring?

Best ResponseYou've already chosen the best response.0I can check my answer using the FOIL method I just don't know the steps to factoring if that makes sense @jdoe0001

Best ResponseYou've already chosen the best response.0ok well.. let's start backwards any ideas on say C) since is very simple \(\bf x^236\) ?

Best ResponseYou've already chosen the best response.0are the answers I put at the bottom of my question right @jdoe0001

jdoe0001

Best ResponseYou've already chosen the best response.0hmm ok well, those are given, but anyhow \(\bf x^236\qquad {\color{brown}{ 6^2=36}}\qquad thus\implies x^26^2 \\ \quad \\ \\ \textit{difference of squares} \\ \quad \\ (ab)(a+b) = a^2b^2\qquad \qquad a^2b^2 = (ab)(a+b)\\ \\ x^26^2\implies (x6)(x+6)\)

Best ResponseYou've already chosen the best response.0okay so I would explain this one by saying the square root of 36 is 6

jdoe0001

Best ResponseYou've already chosen the best response.0yes, or that 36 is the square of 6 and thus it makes it a difference of squares

Best ResponseYou've already chosen the best response.0so that is showing work on factoring?

Best ResponseYou've already chosen the best response.0B) is also simple if we factor 25, we get 5, 5, 1 5*5*1 = 25 if we "multiply" then 5*5 we get the last term if we "add" 5+5, we get the middle term thus \(\begin{array}{cccllll} x^2&+10&+25\\ &\uparrow &\uparrow \\ &5+5&5\cdot 5 \end{array}\implies (x+5)(x+5)\)

Best ResponseYou've already chosen the best response.0okay so if I were to explain it, it would be in order to factor x^2+10x+25 you pull out the GCF which in this case is 5 and simplify to (x+5)(x+5)

jdoe0001
 one year ago
Best ResponseYou've already chosen the best response.0well... 5 is not the GCF, notice \(x^2\) doesn't have a 5 you'd factor out the last term, the constant one and from a combination of two of its factors you ought to get the middle term

Best ResponseYou've already chosen the best response.0so from the original problem of x^2+10x+25 you would factor the 10 and 25 and that's is supposed to be explaining the steps of how you get this answer?

jdoe0001

Best ResponseYou've already chosen the best response.0hmm well... you said you have already covered factoring so...... you should recall that you need to factor out the constant to get the values for the binomials

Best ResponseYou've already chosen the best response.0so by factoring out 25 we get 5*5 which will give us the two numbers we need but then would you take the square root of x cause you have to have two x's in the end

Best ResponseYou've already chosen the best response.0so is this 3x(x2)+4(x2) the final answer and not y^2(3x+4)(x2) @triciaal

Best ResponseYou've already chosen the best response.1I had +2 instead of +4 for the factors but correctly used + 4 for a sum of 2 made the correction dw:1438903609253:dw do you understand all the steps ?

Best ResponseYou've already chosen the best response.0so first you take out the term y^2 then you have y^2(3x^32x8) identify a,b,c 3(8) =24 use 6,4 3x^26x+4x8 3x(x2)+4(x2)

anonymous

Best ResponseYou've already chosen the best response.0so to factor find a,b,c then find the common one and that's it

Best ResponseYou've already chosen the best response.1identify a, b, c multiply a by c and list the factors choose the combination of factors that will add up to b pay attention to the signs rewrite the middle term using the sum of the factors regroup and factor ( the 2 sets ) identify the common term in the 2 sets factor out the common term from the 2 sets what you get is the complete factorization of the original

Best ResponseYou've already chosen the best response.0a is x^2 b is 7x and c is 12

triciaal

Best ResponseYou've already chosen the best response.1we use a, b, c for the general equation

anonymous

Best ResponseYou've already chosen the best response.0okay so bis 7 and c is 12 but im not sure what a is maybe 1

triciaal

Best ResponseYou've already chosen the best response.1a*c = 1* 12 = 12 next step factors of 12

Best ResponseYou've already chosen the best response.1review the instructions also the negatives we want the combination that when added will give b in this case +7 so we use +4 and +3
