Question

Multiply
(3x-5)^2
A.9x^2-30x+25
B.6x^2-10
C.9x^2-25
D.9x^2-15x+25

Answer 1

is it C?

Answer 2

A.9x^2-30x+25

Answer 3

can oyu explain your math @hazem-wardat

Answer 4

I'd much rather that you demonstrate how you got your possible answer than just ask, "is it C?"

(3x-5)^2 is the square of 3x-5, but yes, it's true that you need multiplication to evaluate (3x-5)^2.

@hazem-wardat : Would you please not provide answers; instead, please guide onetrevordude towards finding the correct result on his own. Thank you.

Answer 5

Please do that guiding now, if you can; otherwise I will.

Answer 6

ok isee what i did wrong

Answer 7

Would you, trevor, please show how you are now obtaining the correct result?

Answer 8

i needed to seperate the equations then FOIL

Answer 9

i though to just evenly distribute the exponent

Answer 10

(3x-5)*(3x-5)= 3x*3x+3x*-5+-5*3x+-5*-5

Answer 11

@onetevordude : Actually, we don't "distribute the exponent;" instead, we rewrite (3x-5)^2 as (3x-5)*(3x-5) and use the foil mehtod of multiplying binomials. this is what hazem has done (above).
