Simplifying x(7 + -1x) + 9x = -4 (7 * x + -1x * x) + 9x = -4 (7x + -1x2) + 9x = -4 Reorder the terms: 7x + 9x + -1x2 = -4 Combine like terms: 7x + 9x = 16x 16x + -1x2 = -4 Solving 16x + -1x2 = -4 Solving for variable 'x'. Reorder the terms: 4 + 16x + -1x2 = -4 + 4 Combine like terms: -4 + 4 = 0 4 + 16x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -4 + -16x + x2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + -16x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + -16x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -16x + x2 = 0 + 4 -16x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 -16x + x2 = 4 The x term is -16x. Take half its coefficient (-8). Square it (64) and add it to both sides. Add '64' to each side of the equation. -16x + 64 + x2 = 4 + 64 Reorder the terms: 64 + -16x + x2 = 4 + 64 Combine like terms: 4 + 64 = 68 64 + -16x + x2 = 68 Factor a perfect square on the left side: (x + -8)(x + -8) = 68 Calculate the square root of the right side: 8.246211251 Break this problem into two subproblems by setting (x + -8) equal to 8.246211251 and -8.246211251.Subproblem 1
x + -8 = 8.246211251 Simplifying x + -8 = 8.246211251 Reorder the terms: -8 + x = 8.246211251 Solving -8 + x = 8.246211251 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + x = 8.246211251 + 8 Combine like terms: -8 + 8 = 0 0 + x = 8.246211251 + 8 x = 8.246211251 + 8 Combine like terms: 8.246211251 + 8 = 16.246211251 x = 16.246211251 Simplifying x = 16.246211251Subproblem 2
x + -8 = -8.246211251 Simplifying x + -8 = -8.246211251 Reorder the terms: -8 + x = -8.246211251 Solving -8 + x = -8.246211251 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + x = -8.246211251 + 8 Combine like terms: -8 + 8 = 0 0 + x = -8.246211251 + 8 x = -8.246211251 + 8 Combine like terms: -8.246211251 + 8 = -0.246211251 x = -0.246211251 Simplifying x = -0.246211251Solution
