Question

For what values of x is x2 + 2x = 24 true?

0 -6 and 4
0.4 and 6
04 and 6
O 6 and 4

Answer 1

The values are -6 and 4

Explanation:

First subtract 24 from both sides to get x²+2x-24 = 0. Then factor to get (x+6)(x-4)=0. Finally set each factor = to 0 and solve for x. so x+6=0 and x-4=0 so x=-6 and x=4
