Question

PLEASE HELP!
Factor the polynomial by grouping!
2x^2 -x -3
5x^2 + 34x -7

Answer 1

For the first one,

Find two numbers m and n such that
m x n = -6
m + n = -1

Answer 2

Omg, wait I got it it I just forgot to multiply 2 and 3 note it makes sense.

Answer 3

If you do that, then you'll notice that the two numbers are -3 and 2

so rewrite 2x^2 -x - 3

2x^2 + 2x - 3x - 3

Then factor the first two terms
2x(x + 1)

Then factor the last two terms
-3(x + 1)

So together you have

2x(x + 1) - 3(x + 1)

Then factor out what's common to both factorizations:
(x + 1)(2x - 3)

Answer 4

Well, okay, since you got it, then you can do the second one.

Answer 5

When I do it can you check my answer please math god lol (: thanks
