    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
