Factor out the GCF:
A product of two factors is zero if at least one of the factors is zero. Therefore, your solution set is a={0,4}.
You can put this solution on YOUR website! 2A^2-8A=0
2A(A-4)=0 [factor]
.
2A=0 [set each factor equal to zero and solve for the variable (A)]
2A/2=0/2
A=0
checking:
2(0)^2-8(0)=0
0-0=0
0=0 [checks out]
.
A-4=0
A=4
checking:
2(4)^2-8(4)=0
2(16)-32=0
32-32=0
0=0 [also checks out]
.
so A=0 or A=4
