Find the roots of the equations: 3m22m65=0

A.

(5,133)

B.

(5,133)

C.

(5,133)

D.

(5,133)

Correct answer is B

Find the roots of the equations: 3m22m65=0

= m215m+13m65=0

= 3m(m - 5) + 13( m - 5) = 0

( m - 5)(3m + 13) = 0 

m-5 = 0 or 3m + 13 = 0

therefore, m = 5 or 133

therefore the roots of the quadratic equation = ( 5, 133)
