Simplifying X2 + x + x2 + 3x = 30 Reorder the terms: X2 + x + 3x + x2 = 30 Combine like terms: x + 3x = 4x X2 + 4x + x2 = 30 Solving X2 + 4x + x2 = 30 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-4x' to each side of the equation. X2 + 4x + -4x + x2 = 30 + -4x Combine like terms: 4x + -4x = 0 X2 + 0 + x2 = 30 + -4x X2 + x2 = 30 + -4x Add '-1x2' to each side of the equation. X2 + x2 + -1x2 = 30 + -4x + -1x2 Combine like terms: x2 + -1x2 = 0 X2 + 0 = 30 + -4x + -1x2 X2 = 30 + -4x + -1x2 Simplifying X2 = 30 + -4x + -1x2 Reorder the terms: -30 + X2 + 4x + x2 = 30 + -4x + -1x2 + -30 + 4x + x2 Reorder the terms: -30 + X2 + 4x + x2 = 30 + -30 + -4x + 4x + -1x2 + x2 Combine like terms: 30 + -30 = 0 -30 + X2 + 4x + x2 = 0 + -4x + 4x + -1x2 + x2 -30 + X2 + 4x + x2 = -4x + 4x + -1x2 + x2 Combine like terms: -4x + 4x = 0 -30 + X2 + 4x + x2 = 0 + -1x2 + x2 -30 + X2 + 4x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 -30 + X2 + 4x + x2 = 0 The solution to this equation could not be determined.
