When you factor the equation, you get the following: (x+10)(x+3)=0 Now set x+10=0 and you get x=-10 Set the other part x+3=0 and you get x=-3 Therefore, x=-10 and x=-3 To prove the correctness of the answer substitute in the values: (-10+10)(-10+3) and you get zero (-3+10)(-3+3) and once again you get zero
