2.Factor completely 4x3 + 8x2 - 25x – 50.

(4x2 - 25)(x + 2)

(2x - 2)(2x + 2)(x + 5)

(2x - 5)(2x + 5)(x + 2)

(2x - 5)(2x + 5)(x - 2)

Answer 1

answer only please

Answer 2

no way am I giving answer only

Answer 3

u can work it out if u want

Answer 4

some people dont like showing work so i put that

Answer 5

you can work it out. - I'll help

When you multiply out the factors the terms without x in all end up multiplying to give the constant term in the equation

SO

take the THREE factors without x from the 3 brackets in q1 - and write them here

then multiply them together.....

Answer 6

like I thought - no answer from me .... no answer from you
