Simplifying 5 + 2x(-3) + 4 = 2 + 3x(-1x) Reorder the terms for easier multiplication: 5 + 2 * -3x + 4 = 2 + 3x(-1x) Multiply 2 * -3 5 + -6x + 4 = 2 + 3x(-1x) Reorder the terms: 5 + 4 + -6x = 2 + 3x(-1x) Combine like terms: 5 + 4 = 9 9 + -6x = 2 + 3x(-1x) Remove parenthesis around (-1x) 9 + -6x = 2 + 3x * -1x Reorder the terms for easier multiplication: 9 + -6x = 2 + 3 * -1x * x Multiply 3 * -1 9 + -6x = 2 + -3x * x Multiply x * x 9 + -6x = 2 + -3x2 Solving 9 + -6x = 2 + -3x2 Solving for variable 'x'. Reorder the terms: 9 + -2 + -6x + 3x2 = 2 + -3x2 + -2 + 3x2 Combine like terms: 9 + -2 = 7 7 + -6x + 3x2 = 2 + -3x2 + -2 + 3x2 Reorder the terms: 7 + -6x + 3x2 = 2 + -2 + -3x2 + 3x2 Combine like terms: 2 + -2 = 0 7 + -6x + 3x2 = 0 + -3x2 + 3x2 7 + -6x + 3x2 = -3x2 + 3x2 Combine like terms: -3x2 + 3x2 = 0 7 + -6x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 2.333333333 + -2x + x2 = 0 Move the constant term to the right: Add '-2.333333333' to each side of the equation. 2.333333333 + -2x + -2.333333333 + x2 = 0 + -2.333333333 Reorder the terms: 2.333333333 + -2.333333333 + -2x + x2 = 0 + -2.333333333 Combine like terms: 2.333333333 + -2.333333333 = 0.000000000 0.000000000 + -2x + x2 = 0 + -2.333333333 -2x + x2 = 0 + -2.333333333 Combine like terms: 0 + -2.333333333 = -2.333333333 -2x + x2 = -2.333333333 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 = -2.333333333 + 1 Reorder the terms: 1 + -2x + x2 = -2.333333333 + 1 Combine like terms: -2.333333333 + 1 = -1.333333333 1 + -2x + x2 = -1.333333333 Factor a perfect square on the left side: (x + -1)(x + -1) = -1.333333333 Can't calculate square root of the right side. The solution to this equation could not be determined.
