Question

Factor the expression

x2+2x−15

Answer 1

Can you post a ss plz

Answer 2

I’d say it’s B bc

X + 3 = 3x

And then

X + 12 = 15

So I’m guessing that x = 3

So it would be 3x^2 + 15

Answer 3

what are the steps to get ther though

And also x^2 + 2x = 3x^2

Answer 5

When Factoring x^2+2x-15

First term is: x2 coefficient is 1.

Middle term: +2x coefficient is 2 .

Last term:, the constant is -15

Multiply the coefficient of the first term by the constant

1 • -15 = -15

Find two factors of -15 which has the sum equal to the coefficient of the middle term (Again it is 2)

-15+1=-14

-5+3=-2

-3+5=2

x^2 - 3x + 5x - 15

x • (x-3)

5 • (x-3)

Hence,

(x+5) • (x-3)
