Check if you can factor x^2 + 4, somehow.

(x-2)(x-2)?

FOIL that. You get: x^2 -2x - 2x + 4 = x^2 -4x + 4, so no.

I feel like you have a problem in the question. Are you sure it's not x^2 - 4?

I guess you could complete the square. Or just do long division

Let's solve your equation step-by-step. x2+4x−2=x3−2x+4x x2+4x−2=x3+2x Step 1: Subtract x^3+2x from both sides. x2+4x−2−(x3+2x)=x3+2x−(x3+2x) −x3+x2+2x−2=0 Step 2: Factor left side of equation. (−x+1)(x2−2)=0 Step 3: Set factors equal to 0. −x+1=0 or x2−2=0 x=1

Let's simplify step-by-step. x3−2x+4x =x3+−2x+4x Combine Like Terms: =x3+−2x+4x =(x3)+(−2x+4x) =x3+2x Answer: =x3+2x

what? How is x^2 + 4x - 2 = x^3 - 2x + 4x? even if you multiply all by x you'd get x^3 + 4x^2 -2x
