Answer:

x = -6 x=4

Step-by-step explanation:

x^ 2 + 2 x = 24

Subtract 24 from each side

x ^2 + 2 x-24 = 24-24

x^2 +2x -24 = 0

Factor

What 2 numbers multiply to -24 and add to 2

6*-4 = -24

6+-4 = -2

(x+6) (x-4) =0

Using the zero product property

x+6 =0 x -4=0

x+6-6=0-6 x-4+4=0+4

x = -6 x=4

Answer: The answer is 1,037. You did good with the first three steps but you need to do the same for the last step, because you have 21 you have to find how many times 3 goes into it, which would be 7, and that gives you your full answer of 1,037.
