Find an upper limit for the zeros of 2 x4 - 7 x3 + 4 x2 + 7 x - 6 = 0

Let's solve your equation step-by-step. 2 x4 - 7 x3 + 4 x2 + 7x - 6 = 0 Step 1: Factor left side of equation. (x+1) (x-1) (x-2) (2x - 3) = 0 Step 2: Set factors equal to 0. x+1 = 0 or x - 1 = 0 or x - 2 = 0 or 2x - 3 = 0 x = - 1 or x = 1 or x = 2 or x = 32 Answer: x = - 1 or x = 1 or x = 2 or x = 3 2
