Question

Use long division for (2x^2 + 10x +12) / (x + 3).
I tried it, but I'm lost.

Answer 1

you have to use long division?
what is 2x^ ? what is the power?

Answer 2

2^2

Answer 3

(2x^2 + 10 x + 12) / (x + 3) [Factoring numerator]
= (2x + 4) (x + 3) / (x + 3) [Since you have (x + 3) in both numerator and denominator, they cancel out]
= (2x + 4)

Answer 4

okay good, so what you do is,

factor out (2x^2 + 10x +12) into the usual
(x+y) (x+y) type of thing.

Use the square thing (2x + 4)(x + 3) / (x + 3)
Use cancellation and then you get 2x + 4

Answer 5

Got it or is it confusing?

Answer 6

You need to recognize similar values terms and find which to cross out and which can be simplified

Answer 7

I did that

Answer 8

so then your asnwer should be 2x+4

Answer 9

*answer

Answer 10

did u get it now

Answer 11

Answer 12

because you need 2x+4 lol
