Question

Help me solve x^2 + 2x -3 = 0

Answer 1

Alright, do you know splitting the middle term method? It could be used here..

Answer 2

My first step was (X + 3) (X - 1) = 0; second step was (X + 3) = 0 and (X - 1) = 0; answer was X = -3 x = 1. Is that correct?

Answer 3

Yup, you are right! Good work! :DD

Answer 4

I'm very new. How do I thank you?

Answer 5

Answer 8

The area of this rectangle is 80ft^2. What is the length and width? One side is X. The other side is X + 16. I started with 80 = x (X + 16)

Answer 9

That's right. :)

Answer 10

What would be your next step? c:

Answer 11

If that's right, then I get 80 = x^2 + 16x

Answer 12

I think you will have to take 80 to the other side and do what u did earlier.. Not sure.

Answer 13

Ok, I'll try that! Thank you

Answer 14
