Given:
given equation is (x-8) (x+7) = 0.
Find:
we have to solve the equation by zero product principle.
Explanation:
if two factors of an equation is zero, then by zero product principle, either first factor is equal to zero or second factor is equal to zero.
Therefore,
for (x-8) (x+7) = 0
either x- 8 = 0 or x + 7 = 0
either x = 8 or x = -7
Therefore, x =8 . -7 are the solutions.
