Question

Which of the following is a solution of x2 + 6x = -22?

Answer 1

Do you know about the quadratic formula?

Answer 2

yes i do

Answer 3

Okay, great! So if we moved all of the variables and numbers onto the same side, what would the equation look like?

Answer 4

x^2+6x-22

Answer 5

Close, So if we had x^2 + 6x = -22, and we wanted to get all of the terms onto one side, we would have to add 22 to each side, right?

Answer 6

oh yea

Answer 7

So if we added 22 to both sides, what would be the resulting equation?

Answer 8

x^2+6x+22=0?
or would we not need the =0

Answer 9

That's correct! You would need the "= 0" because it's an equation. So now that we have the terms on the left side and the whole thing set equal to 0, we can use the quadratic formula to find the solution(s) to the equation.
