Use the zero product property to find the solutions to the equation x2 + x - 30 = 12.
Solution:
Zero product property, also known as zero product principle states that if p × q = 0 , then p = 0 or q = 0 or both p = 0 and q = 0 .
Given: Quadratic equation is x2 + x - 30 = 12
It can be written as
x2 + x - 30 - 12 = 0
x2 + x - 42 = 0
By splitting the middle term
x2 + 7x - 6x - 42 = 0
Taking out the common terms
x(x + 7) - 6(x + 7) = 0
So we get,
(x + 7)(x - 6) = 0
Now according to the zero product property,
either x + 7 = 0 or x - 6 = 0
x = -7 or x = 6
Therefore, the solution is -7 or 6.
Use the zero product property to find the solutions to the equation x2 + x - 30 = 12.
Summary:
Using the zero product property, the solutions to the equation x2 + x - 30 = 12 is -7 or 6.
