The solutions for x are the values such that each factor of P(x) is equal to zero. For example, if one factor is (x + 7), you just need to solve x + 7 = 0 ==> x = -7. Do that for each of the given factors, and see which possible answer corresponds to all of the values you found.

Set each factor to zero and determine the value of the variable that makes that simple equation true
For example,
(x + 7)
x + 7 = 0
x = - 7

Set each bracket equal to zero, then solve for x. It will give you the opposite of every number in the bracket. Like this, (x+7)=0, x=0-7, x= -7.

just change the sign around in each bracket, easy stuff
