Distribute z zc + 5z Now distribute -8 -40 - 8c Giving us: zc + 5z - 40 - 8c
omg, i can't figure these out for the life for of me.
Ok, lets take this step by step.
Looking at the equation given, we have to use the distributive property. What can we distribute here?
z or -8
wait let absorb this?
z AND -8 When we distribute z to (c + 5) we get?
Right! Now lets distribute -8 to (5 + c)
And we get?
Now lets put it all together, to get?
Dont forget, its ( -40 - 8c) Since that cannot be simplified further, that will cluded to be our answer.
ok i checked the book and the answer is (c+5)(z-8)
What were the directions to this problem? Because the way you wrote it, Baala and I cocnluded to t he same answer.
i know i got that also hold on.... it is factoring polynomials.
Haha, then this would be solved in a different more convulted way.
u understand it. by the way thanks for your help.
Well its quite easy actually. Your original question was: z ( c+ 5 ) - 8 (5 + c) You see how the expressions in the paranthesis are the same? They are both ( c + 5) right? Therefore, it creates one portion of this factorial polynomial. ( c + 5) Now you see the constants outside the paranthesis? Lets put those "together" to get z - 8 Correct? This creates another portion of the factorial polynomial. (z - 8) Put these both together and you get the answer to be: (z - 8 ) ( c+ 5)
Anytime sweetie =)
o. o. see that makes sense... lol
omg, it has been 20+ yrs since i have dona any algebra... a bit rusty... lol
Well then you must be quite older than me! :P
Keep intact with Openstudy to revive the past lessons on Algebra
lol yeah i am up there... lol thanks sooooo much...
No problemo =D the pleasure is mine
z(c+5) - 8(5+c)= (z - 8) (5+c)
