You can solve this 2 ways: plug in all of the options or solve for x. i going to solve for x.
given: x^2+2x=24 (subtract 24 on both sides to get make it look like x^2+x+1)
x^2+2x-24=0 (now factor x^2+2x-24 out)
<span>x^2+2x-24 --> (x-4)(x+6) </span> new equation: <span>(x-4)(x+6)=0 (now make them both equl zero)
new equaions: </span>x-4=0 x+6=0 <span> (now solve for x for both)
x-4=0 x+6=0 x=4 x=-6 your <span>answer is 4 and -6. if you were not taught how to do what i just did then i can message you how to plug those numbers into </span></span><span> x^2+2x=24 to find the answer.</span>
