Question

Find the possible value or values of n in the quadratic equation 2n2 - 7n + 6 = 0.

A. n = 32, n = 2
B. n = 1, n = 3
C.n=6, n = 0
D. n = -2, n = -32

Answer 1

the answer will be 3/2 or 2

Explanation:

2n^2-7n+6

2n^2-4n-3n+6=0

2n (n-2)-3 (n-2)=0

(2n-3)(n-2)=0

(2n-3)=0------------(i)

(n-2)=0-----------(ii)

from equ. (i) from equ. (ii)

2n-3=0 n-2=0

2n=3 n=2

n=3/2
