Given the equation 2x 87x 5 0 Find all solutions for x x
Given the equation: (2x - 87)(x + 5) = 0 Find all solutions for x:
x = -5
x = 87/2 or -5
x = -87 or 5
x = -87/2 or 5
Solution
(2x - 87)(x + 5) = 0
By zero factor property, we can equate each factor to 0 :
2x - 87 = 0 ---> 2x = 87 ----> x = 87/2
x + 5 = 0 ----> x = 0 - 5 ----> x = -5
So, 87/2 and -5
Option B
