Question

can someone help me answer this question please?

an expression is shown below:
2x^3y+18xy-10x^2y-90y


part a.) rewrite the expression so that the the GCF is factored completely.

Answer 1

the GCF is 2 so you will divide each of the coefficients by 2
2(x^3y +9xy-5x^2y -45y

Answer 2

sooo 2(x^3y +9xy-5x^2y -45y) would be new expression if the expression was factored completely?

Answer 3

yes

Answer 4

can you help me with part b and c?

Answer 5

@sleepyjess

Answer 6

yes

Answer 7

i will try at least

Answer 8

part b.) rewrite the expression completely factored show all the steps

Answer 9

part c.)if the two middle terms were switched the expression became 3x^3y-9x^2y+12xy-36ywould the factored expression no longer be equivalent to your answer in part b? explain resoning

Answer 10

i honestly don't completely remember how to factor 4 term polynomials but i think you have to do it by grouping if you know how to

Answer 11

@shamil98 ???

Answer 12

for a, the gcf is 2y not 2.

Answer 13

@shamil98 how would you answer part b and c?

Answer 14

2y(x^3 - 5x^2 + 9x - 45)
just factor the trinomial in the parentheses.

Answer 15

how do you do that?

Answer 16

@shamil98

Answer 17

okay??? no reply????

Answer 18

@Luigi0210 ?

Answer 19

2y (x^3 - 5x^2 + 9x - 45) =
2y (x^2 + 9)(x - 5)
