Simplifying 3(x + 2) * x = -8 Reorder the terms: 3(2 + x) * x = -8 Reorder the terms for easier multiplication: 3x(2 + x) = -8 (2 * 3x + x * 3x) = -8 (6x + 3x2) = -8 Solving 6x + 3x2 = -8 Solving for variable 'x'. Reorder the terms: 8 + 6x + 3x2 = -8 + 8 Combine like terms: -8 + 8 = 0 8 + 6x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 2.666666667 + 2x + x2 = 0 Move the constant term to the right: Add '-2.666666667' to each side of the equation. 2.666666667 + 2x + -2.666666667 + x2 = 0 + -2.666666667 Reorder the terms: 2.666666667 + -2.666666667 + 2x + x2 = 0 + -2.666666667 Combine like terms: 2.666666667 + -2.666666667 = 0.000000000 0.000000000 + 2x + x2 = 0 + -2.666666667 2x + x2 = 0 + -2.666666667 Combine like terms: 0 + -2.666666667 = -2.666666667 2x + x2 = -2.666666667 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -2.666666667 + 1 Reorder the terms: 1 + 2x + x2 = -2.666666667 + 1 Combine like terms: -2.666666667 + 1 = -1.666666667 1 + 2x + x2 = -1.666666667 Factor a perfect square on the left side: (x + 1)(x + 1) = -1.666666667 Can't calculate square root of the right side. The solution to this equation could not be determined.
