Question

Rewrite the expression by factoring out (x+4)
3x^2(x+4)-7(x+4)

Answer 1

@sleepyhead314 can you help me with this?

Answer 2

it was like the idea I showed you before ^_^

ab - ac = a (b - c)

(3x^2)(x+4) - (7)(x+4)

Answer 3

3x^3+4-7+4x?

Answer 4

Answer 5

not quite!

for example, if I had
2x^2(x+5) - 9(x+5)
I would get
(x+5)(2x^2 - 9)

Answer 6

(x+4)(3x^3-7)?

Answer 7

so very very close!!!

just x^2 not x^3 ;)

Answer 8

(x+4)(3x^2-7)

Answer 9

PERFECT

Answer 10

*throws confetti*

Answer 11

Answer 12

I think that's the answer ;P

Answer 13

but it says factor out (X+4)?

Answer 14

yep ^_^
means to put the (x+4) in front

(x+4)(3x^2-7)

Answer 15
