Question

Zero product property

x(2x+4)(x+5)=0

A) x=0, x=-2, X=-5
B) x=0, x=2, x=5
C) x greater than or equal to 0
D) x=-2, x=5

Answer 1

2x^2+4(x+5)=0
2x^3+10x^2+2x^3+20=0
4^2+10x^2+20=0

Answer 2

A

Explanation:

Using ZPP we get x = 0, 2x + 4 = 0, x + 5 = 0. Solving these, we get x = 0, x = -2, x = -5.
