Question

What's the value if m 2m^2-m-3

Answer 1

Answer:

m = 1/2

m = -1

Explanation:

Step 1  - Let y=0.

2m^2-m-3 = 0

Step 2 - Factor

(2m  - 3 )( m   +      1 ) = 0      

Step 3  

2m-1 = 0                m +1 = 0

Step 4 - Solve

2m = 1 (divide 2 on both sides)        m+1 = 0 (subtract 1 on both sides)

m = 1/2                                                 m = -1
