To solve the equation, we first need to simplify it by combining like terms on both sides.

2x^2 - 5 = x^2 - 4x

First, move all terms to one side of the equation:

2x^2 - x^2 + 4x - 5 =
x^2 + 4x - 5 = 0

Next, factor the quadratic equation:

(x + 5)(x - 1) = 0

Setting each factor to zero:

x + 5 =
x = -5

x - 1 =
x = 1

Therefore, the solutions to the equation are x = -5 and x = 1.
