Question

The roots of the quadratic equation x² + 7x = 0 are 

A) 0, 7 

B) 7, -7 

C) -7, -7 

D) 0, -7

Answer 1

Correct option is (D) 0, -7

\(x^2+7x=0\)

\(\Rightarrow\) x (x+7) = 0

\(\Rightarrow\) x = 0 or x+7 = 0

\(\Rightarrow\) x = 0 or x = -7

Hence, roots of quadratic equation \(x^2+7x=0\) are 0 and -7.

Answer 2

Correct option is D) 0, -7
