Blaine Ray · Answer 1

Answer: n=2

Step-by-step explanation:

Let's solve your equation step-by-step.

2n2-n-4=2

Step 1: Subtract 2 from both sides.

2n2-n-4-2=2-2

2n2-n-6=0

Step 2: Factor left side of equation.

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

Step 3: Set factors equal to 0.

2n+3=0 or n-2=0

n = - 3/2 or n=2
