The roots of a quadratic equation are 7 and -3. Which quadratic equation has these roots? (x + 7) (x – 3) = 0

(x - 7) (x + 3) = 0

(x – 7) (x – 3) = 0

(x + 7) (x + 3) = 0

The answer is (x - 7) (x + 3) = 0

Explanation: Put both equations equal to 0, so it looks like this: (x - 7) = 0 (x + 3) = 0
It doesn’t matter what you do first but I’ll start with (x - 7) = 0
First you remove the parenthesis
x - 7 = 0
Next you add the 7 on both sides. You do this to cancel the 7 so that the x is by itself.
x = 7
It’s the same thing for the (x + 3) = 0 but I’ll show you anyways
Remove parentheses
x + 3 = 0
Subtract the 3 from both sides that way the 3 cancels out and the x is on its own
x = -3

You're doing something i dont know how to do but search up on google slope calculator maybe that will get you there

It would be very great if u would let me take your dog home forever you i love you ti so much carmen you don’t even know bby
