Zero Product Property
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
(x + 6)(x - 6)
No, there cannot be a zero in any scale factor.
Yes.
a(-14-a) = 0 so a = 0 or a = -14
100x2-81
4(x + 1) = 0.
D is the choice that is not true.
