Question

what are the roots of the quadratic equation 2n square+5n+2=0​

Answer 1

Answer: -1/2 or -2

Step-by-step explanation:

2n^2+5n+2=

By factorisation:-

2n^2+n+4n+2=

2n(n+2)+1(n+2) [Taking (n+2) as common]

(2n+1) (n+2)

There fore the roots of the quadratic equation 2n square+5n+2=0 are -1/2 or -2

Answer 2

2n2+5n+2=0

n= -5-√41/4= -2.851

n= -5+√41/4= 0.351
