Simplifying x(2x + -4) = 7(x + 4) Reorder the terms: x(-4 + 2x) = 7(x + 4) (-4 * x + 2x * x) = 7(x + 4) (-4x + 2x2) = 7(x + 4) Reorder the terms: -4x + 2x2 = 7(4 + x) -4x + 2x2 = (4 * 7 + x * 7) -4x + 2x2 = (28 + 7x) Solving -4x + 2x2 = 28 + 7x Solving for variable 'x'. Reorder the terms: -28 + -4x + -7x + 2x2 = 28 + 7x + -28 + -7x Combine like terms: -4x + -7x = -11x -28 + -11x + 2x2 = 28 + 7x + -28 + -7x Reorder the terms: -28 + -11x + 2x2 = 28 + -28 + 7x + -7x Combine like terms: 28 + -28 = 0 -28 + -11x + 2x2 = 0 + 7x + -7x -28 + -11x + 2x2 = 7x + -7x Combine like terms: 7x + -7x = 0 -28 + -11x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -14 + -5.5x + x2 = 0 Move the constant term to the right: Add '14' to each side of the equation. -14 + -5.5x + 14 + x2 = 0 + 14 Reorder the terms: -14 + 14 + -5.5x + x2 = 0 + 14 Combine like terms: -14 + 14 = 0 0 + -5.5x + x2 = 0 + 14 -5.5x + x2 = 0 + 14 Combine like terms: 0 + 14 = 14 -5.5x + x2 = 14 The x term is -5.5x. Take half its coefficient (-2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. -5.5x + 7.5625 + x2 = 14 + 7.5625 Reorder the terms: 7.5625 + -5.5x + x2 = 14 + 7.5625 Combine like terms: 14 + 7.5625 = 21.5625 7.5625 + -5.5x + x2 = 21.5625 Factor a perfect square on the left side: (x + -2.75)(x + -2.75) = 21.5625 Calculate the square root of the right side: 4.643543905 Break this problem into two subproblems by setting (x + -2.75) equal to 4.643543905 and -4.643543905.Subproblem 1
x + -2.75 = 4.643543905 Simplifying x + -2.75 = 4.643543905 Reorder the terms: -2.75 + x = 4.643543905 Solving -2.75 + x = 4.643543905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = 4.643543905 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = 4.643543905 + 2.75 x = 4.643543905 + 2.75 Combine like terms: 4.643543905 + 2.75 = 7.393543905 x = 7.393543905 Simplifying x = 7.393543905Subproblem 2
x + -2.75 = -4.643543905 Simplifying x + -2.75 = -4.643543905 Reorder the terms: -2.75 + x = -4.643543905 Solving -2.75 + x = -4.643543905 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.75' to each side of the equation. -2.75 + 2.75 + x = -4.643543905 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + x = -4.643543905 + 2.75 x = -4.643543905 + 2.75 Combine like terms: -4.643543905 + 2.75 = -1.893543905 x = -1.893543905 Simplifying x = -1.893543905Solution
