Simplifying 4x(x + 8) = (7x + -16) Reorder the terms: 4x(8 + x) = (7x + -16) (8 * 4x + x * 4x) = (7x + -16) (32x + 4x2) = (7x + -16) Reorder the terms: 32x + 4x2 = (-16 + 7x) Remove parenthesis around (-16 + 7x) 32x + 4x2 = -16 + 7x Solving 32x + 4x2 = -16 + 7x Solving for variable 'x'. Reorder the terms: 16 + 32x + -7x + 4x2 = -16 + 7x + 16 + -7x Combine like terms: 32x + -7x = 25x 16 + 25x + 4x2 = -16 + 7x + 16 + -7x Reorder the terms: 16 + 25x + 4x2 = -16 + 16 + 7x + -7x Combine like terms: -16 + 16 = 0 16 + 25x + 4x2 = 0 + 7x + -7x 16 + 25x + 4x2 = 7x + -7x Combine like terms: 7x + -7x = 0 16 + 25x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 4 + 6.25x + x2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + 6.25x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + 6.25x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 6.25x + x2 = 0 + -4 6.25x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 6.25x + x2 = -4 The x term is 6.25x. Take half its coefficient (3.125). Square it (9.765625) and add it to both sides. Add '9.765625' to each side of the equation. 6.25x + 9.765625 + x2 = -4 + 9.765625 Reorder the terms: 9.765625 + 6.25x + x2 = -4 + 9.765625 Combine like terms: -4 + 9.765625 = 5.765625 9.765625 + 6.25x + x2 = 5.765625 Factor a perfect square on the left side: (x + 3.125)(x + 3.125) = 5.765625 Calculate the square root of the right side: 2.401171589 Break this problem into two subproblems by setting (x + 3.125) equal to 2.401171589 and -2.401171589.Subproblem 1
x + 3.125 = 2.401171589 Simplifying x + 3.125 = 2.401171589 Reorder the terms: 3.125 + x = 2.401171589 Solving 3.125 + x = 2.401171589 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.125' to each side of the equation. 3.125 + -3.125 + x = 2.401171589 + -3.125 Combine like terms: 3.125 + -3.125 = 0.000 0.000 + x = 2.401171589 + -3.125 x = 2.401171589 + -3.125 Combine like terms: 2.401171589 + -3.125 = -0.723828411 x = -0.723828411 Simplifying x = -0.723828411Subproblem 2
x + 3.125 = -2.401171589 Simplifying x + 3.125 = -2.401171589 Reorder the terms: 3.125 + x = -2.401171589 Solving 3.125 + x = -2.401171589 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.125' to each side of the equation. 3.125 + -3.125 + x = -2.401171589 + -3.125 Combine like terms: 3.125 + -3.125 = 0.000 0.000 + x = -2.401171589 + -3.125 x = -2.401171589 + -3.125 Combine like terms: -2.401171589 + -3.125 = -5.526171589 x = -5.526171589 Simplifying x = -5.526171589Solution
