Simplifying (-9x + 8) * x + 7x(1x + 10) + -3 = 0 Reorder the terms: (8 + -9x) * x + 7x(1x + 10) + -3 = 0 Reorder the terms for easier multiplication: x(8 + -9x) + 7x(1x + 10) + -3 = 0 (8 * x + -9x * x) + 7x(1x + 10) + -3 = 0 (8x + -9x2) + 7x(1x + 10) + -3 = 0 Reorder the terms: 8x + -9x2 + 7x(10 + 1x) + -3 = 0 8x + -9x2 + (10 * 7x + 1x * 7x) + -3 = 0 8x + -9x2 + (70x + 7x2) + -3 = 0 Reorder the terms: -3 + 8x + 70x + -9x2 + 7x2 = 0 Combine like terms: 8x + 70x = 78x -3 + 78x + -9x2 + 7x2 = 0 Combine like terms: -9x2 + 7x2 = -2x2 -3 + 78x + -2x2 = 0 Solving -3 + 78x + -2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 1.5 + -39x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + -39x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + -39x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + -39x + x2 = 0 + -1.5 -39x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 -39x + x2 = -1.5 The x term is -39x. Take half its coefficient (-19.5). Square it (380.25) and add it to both sides. Add '380.25' to each side of the equation. -39x + 380.25 + x2 = -1.5 + 380.25 Reorder the terms: 380.25 + -39x + x2 = -1.5 + 380.25 Combine like terms: -1.5 + 380.25 = 378.75 380.25 + -39x + x2 = 378.75 Factor a perfect square on the left side: (x + -19.5)(x + -19.5) = 378.75 Calculate the square root of the right side: 19.461500456 Break this problem into two subproblems by setting (x + -19.5) equal to 19.461500456 and -19.461500456.Subproblem 1
x + -19.5 = 19.461500456 Simplifying x + -19.5 = 19.461500456 Reorder the terms: -19.5 + x = 19.461500456 Solving -19.5 + x = 19.461500456 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '19.5' to each side of the equation. -19.5 + 19.5 + x = 19.461500456 + 19.5 Combine like terms: -19.5 + 19.5 = 0.0 0.0 + x = 19.461500456 + 19.5 x = 19.461500456 + 19.5 Combine like terms: 19.461500456 + 19.5 = 38.961500456 x = 38.961500456 Simplifying x = 38.961500456Subproblem 2
x + -19.5 = -19.461500456 Simplifying x + -19.5 = -19.461500456 Reorder the terms: -19.5 + x = -19.461500456 Solving -19.5 + x = -19.461500456 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '19.5' to each side of the equation. -19.5 + 19.5 + x = -19.461500456 + 19.5 Combine like terms: -19.5 + 19.5 = 0.0 0.0 + x = -19.461500456 + 19.5 x = -19.461500456 + 19.5 Combine like terms: -19.461500456 + 19.5 = 0.038499544 x = 0.038499544 Simplifying x = 0.038499544Solution
