Any ideas? Hint: a difference of squares can be factored into the sum of two numbers times their difference.

Hey! Ok first we write 36 as a square in order to express x2-36 as a difference squares so what do we get?
jagr2713
  • jagr2713
so we are just writing 36 as a square

I barley started learning this, since a square is 4 is it 36/4? Im just taking a guess?

v^2 — 36 = v^2 — 6^2
jagr2713
  • jagr2713
Well it was like this 6^2 before right? so they put it into this 36 b.c 6^2=36 so now they want it back to 6^2 @ninowletonzalez06
jagr2713
  • jagr2713
you get it @ninowletonzalez06
jagr2713
  • jagr2713
so if we put it back to 6^2 we get \[v ^{2}-6^{2}\]

Have you studied the FOIL method?

so im thinking it will be A or D?

Good so net we factor the difference of two squares
jagr2713
  • jagr2713
next*
jagr2713
  • jagr2713
so we factor the difference of two square and what do we get
anonymous
  • anonymous
since the symbol is subtraction it should be D since both of the signs are (-)
jagr2713
  • jagr2713
Nope its not b.c we factoring the difference
jagr2713
  • jagr2713
your on the right track :D

Yea its V2 but we factored it out so do the same for the other and yes it 6^2 sorry :D

(v+6)•(v-6) =(v+6)v-(v+6)6
jagr2713
  • jagr2713
Ok lets try this :D Lets use difference of squares which the formula is \[a ^{2}-b ^{2}=(a+b)(a-b)\]
jagr2713
  • jagr2713
Plug it in @ninowletonzalez06
anonymous
  • anonymous
(v+6)(v-6)
jagr2713
  • jagr2713
Correct
jagr2713
  • jagr2713
Great job :D
anonymous
  • anonymous
so A is your answer!
jagr2713

Anytime you get this sort of question just the formula i gave above and Yes A is correct :D

Determine if the expression is a perfect square and if it is, factor it. a2 – 8a – 16 A. (4a + 1)2 B. (a + 4)(a – 4) C. (a – 4)(a – 4) D. not a perfect square
