Simplifying 5 + (4 + -1x) * x = 21 Reorder the terms for easier multiplication: 5 + x(4 + -1x) = 21 5 + (4 * x + -1x * x) = 21 5 + (4x + -1x2) = 21 Solving 5 + 4x + -1x2 = 21 Solving for variable 'x'. Reorder the terms: 5 + -21 + 4x + -1x2 = 21 + -21 Combine like terms: 5 + -21 = -16 -16 + 4x + -1x2 = 21 + -21 Combine like terms: 21 + -21 = 0 -16 + 4x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 16 + -4x + x2 = 0 Move the constant term to the right: Add '-16' to each side of the equation. 16 + -4x + -16 + x2 = 0 + -16 Reorder the terms: 16 + -16 + -4x + x2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -4x + x2 = 0 + -16 -4x + x2 = 0 + -16 Combine like terms: 0 + -16 = -16 -4x + x2 = -16 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -16 + 4 Reorder the terms: 4 + -4x + x2 = -16 + 4 Combine like terms: -16 + 4 = -12 4 + -4x + x2 = -12 Factor a perfect square on the left side: (x + -2)(x + -2) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined.
