You can put this solution on YOUR website! Should the equation be:
x^2-4x-5=0 ??
.
If so,
x^2-4x-5=0
Factoring:
(x-5)(x+1)=0
Set each factor equal to zero and solve for x:
x-5=0
x=5
.
and
.
x+1=0
x=-1
Check each answer by plugging values of x back into the original equation:
x^2-4x-5=0
(5)^2-4(5)-5=0
25-20-5=0
0=0 This value checks out.
.
x^2-4x-5=0
(-1)^2-4(-1)-5=0
1+4-5=0
5-5=0
0=0 This value also checks out.
