Simplifying 4x(x + 7) + -4 = 18 + 5x Reorder the terms: 4x(7 + x) + -4 = 18 + 5x (7 * 4x + x * 4x) + -4 = 18 + 5x (28x + 4x2) + -4 = 18 + 5x Reorder the terms: -4 + 28x + 4x2 = 18 + 5x Solving -4 + 28x + 4x2 = 18 + 5x Solving for variable 'x'. Reorder the terms: -4 + -18 + 28x + -5x + 4x2 = 18 + 5x + -18 + -5x Combine like terms: -4 + -18 = -22 -22 + 28x + -5x + 4x2 = 18 + 5x + -18 + -5x Combine like terms: 28x + -5x = 23x -22 + 23x + 4x2 = 18 + 5x + -18 + -5x Reorder the terms: -22 + 23x + 4x2 = 18 + -18 + 5x + -5x Combine like terms: 18 + -18 = 0 -22 + 23x + 4x2 = 0 + 5x + -5x -22 + 23x + 4x2 = 5x + -5x Combine like terms: 5x + -5x = 0 -22 + 23x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -5.5 + 5.75x + x2 = 0 Move the constant term to the right: Add '5.5' to each side of the equation. -5.5 + 5.75x + 5.5 + x2 = 0 + 5.5 Reorder the terms: -5.5 + 5.5 + 5.75x + x2 = 0 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + 5.75x + x2 = 0 + 5.5 5.75x + x2 = 0 + 5.5 Combine like terms: 0 + 5.5 = 5.5 5.75x + x2 = 5.5 The x term is 5.75x. Take half its coefficient (2.875). Square it (8.265625) and add it to both sides. Add '8.265625' to each side of the equation. 5.75x + 8.265625 + x2 = 5.5 + 8.265625 Reorder the terms: 8.265625 + 5.75x + x2 = 5.5 + 8.265625 Combine like terms: 5.5 + 8.265625 = 13.765625 8.265625 + 5.75x + x2 = 13.765625 Factor a perfect square on the left side: (x + 2.875)(x + 2.875) = 13.765625 Calculate the square root of the right side: 3.71020552 Break this problem into two subproblems by setting (x + 2.875) equal to 3.71020552 and -3.71020552.Subproblem 1
x + 2.875 = 3.71020552 Simplifying x + 2.875 = 3.71020552 Reorder the terms: 2.875 + x = 3.71020552 Solving 2.875 + x = 3.71020552 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.875' to each side of the equation. 2.875 + -2.875 + x = 3.71020552 + -2.875 Combine like terms: 2.875 + -2.875 = 0.000 0.000 + x = 3.71020552 + -2.875 x = 3.71020552 + -2.875 Combine like terms: 3.71020552 + -2.875 = 0.83520552 x = 0.83520552 Simplifying x = 0.83520552Subproblem 2
x + 2.875 = -3.71020552 Simplifying x + 2.875 = -3.71020552 Reorder the terms: 2.875 + x = -3.71020552 Solving 2.875 + x = -3.71020552 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.875' to each side of the equation. 2.875 + -2.875 + x = -3.71020552 + -2.875 Combine like terms: 2.875 + -2.875 = 0.000 0.000 + x = -3.71020552 + -2.875 x = -3.71020552 + -2.875 Combine like terms: -3.71020552 + -2.875 = -6.58520552 x = -6.58520552 Simplifying x = -6.58520552Solution
