How do you solve x-1 plus x2-x plus x3-x2 plus x4-x3?
x4 - 1.We can not "solve" this as we have not been told the value of x. However, we can simplify this expression:We have an x and a minus x here which will cancel out. Likewise the x2 and x3 will cancel out with the -x2 and -x3 respectively. This therefore leaves us with just x4 - 1.

How do you solve x³-4x equals 0 algebraically?
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.

How do you solve x3 plus x2-x equals 0?
x3 + x2 - x = 0 ∴ x2 + x - 1 = 0 ∴ x2 + x + 0.25 = 1.25 ∴ (x + 0.5)2 = 1.25 ∴ x + 0.5 = ± 1.251/2 ∴ x = -0.5 ± 1.251/2
