Step-by-step explanation:the steps he took are correct but the answer of x is somehow wrong because

(x+2)=0

x = -2

and not x = 2

Answer:He should have subtracted 2 from each side to find the solution for x+2 =0

Step-by-step explanation:(x + 2)(x – 7) = 0

Using the zero product property

x+2 = 0 x-7=0

x+2-2=0-2 x-7+7=0+7

x = -2 x=7

He should have subtracted 2 from each side to find the solution for x+2 =0
