Question

Find the value of m if the roots of the quadratic
equation mx² + 3x +2=0are 2 or -1/2
​

Answer 1

to find the value of m simply put the value of its zeroes that is given.

4m + 6 + 2 = 0

4m + 8 = 0

4m = -8

m = -8/4

m = -2

Answer 2

Solution:

Substitute m=2 in given quadratic equation mx²+3x+2=0, we get

=> m(2²)+3×2+2=0

=> 4m+6+2=0

=> 4m+8 = 0

=> 4m = -8

=> m = (-8)/4

=> m = -2

Therefore,

m = -2
