Find the quadratic equation whose roots are x = -2 or x = 7

A.  x2 + 2x – 7 = 0
B. x2 + 2x + 7 = 0
C. x2 + 5x + 14 = 0
D. x2 + 5x – 14 = 0
E.  x2 – 5x – 14 = 0

Correct Answer: Option E

E.  x2 – 5x – 14 = 0

Explanation
x + 2 and x – 7 are factors
(x+2)(x+7) = 0

x(x-7) + 2(x-7) = 0

x2 – 7x + 2x – 14 = 0

x2 – 5x – 14 = 0
