Question

Solve equation by using the quadratic formula.
2 x squared + 13 x = 0

Answer 1

x = 0 or –13/2

Explanation:

2x² + 13x = 0

Using quadratic formula,

Let a=2, b=13 and c=0

–b± (√b²–4ac)/2(a)

–13 ± (√13² – 4(2)(0))/2(2)

–13 ± (√169)/4

(– 13 ± 13)/4

x= (–13 + 13)/4 or (–13–13)/4

x = 0 or – 13/2
