Simplifying x2 + 8x = (x + 5)(2 + -8) Reorder the terms: 8x + x2 = (x + 5)(2 + -8) Reorder the terms: 8x + x2 = (5 + x)(2 + -8) Combine like terms: 2 + -8 = -6 8x + x2 = (5 + x)(-6) Reorder the terms for easier multiplication: 8x + x2 = -6(5 + x) 8x + x2 = (5 * -6 + x * -6) 8x + x2 = (-30 + -6x) Solving 8x + x2 = -30 + -6x Solving for variable 'x'. Reorder the terms: 30 + 8x + 6x + x2 = -30 + -6x + 30 + 6x Combine like terms: 8x + 6x = 14x 30 + 14x + x2 = -30 + -6x + 30 + 6x Reorder the terms: 30 + 14x + x2 = -30 + 30 + -6x + 6x Combine like terms: -30 + 30 = 0 30 + 14x + x2 = 0 + -6x + 6x 30 + 14x + x2 = -6x + 6x Combine like terms: -6x + 6x = 0 30 + 14x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-30' to each side of the equation. 30 + 14x + -30 + x2 = 0 + -30 Reorder the terms: 30 + -30 + 14x + x2 = 0 + -30 Combine like terms: 30 + -30 = 0 0 + 14x + x2 = 0 + -30 14x + x2 = 0 + -30 Combine like terms: 0 + -30 = -30 14x + x2 = -30 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = -30 + 49 Reorder the terms: 49 + 14x + x2 = -30 + 49 Combine like terms: -30 + 49 = 19 49 + 14x + x2 = 19 Factor a perfect square on the left side: (x + 7)(x + 7) = 19 Calculate the square root of the right side: 4.358898944 Break this problem into two subproblems by setting (x + 7) equal to 4.358898944 and -4.358898944.Subproblem 1
x + 7 = 4.358898944 Simplifying x + 7 = 4.358898944 Reorder the terms: 7 + x = 4.358898944 Solving 7 + x = 4.358898944 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 4.358898944 + -7 Combine like terms: 7 + -7 = 0 0 + x = 4.358898944 + -7 x = 4.358898944 + -7 Combine like terms: 4.358898944 + -7 = -2.641101056 x = -2.641101056 Simplifying x = -2.641101056Subproblem 2
x + 7 = -4.358898944 Simplifying x + 7 = -4.358898944 Reorder the terms: 7 + x = -4.358898944 Solving 7 + x = -4.358898944 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -4.358898944 + -7 Combine like terms: 7 + -7 = 0 0 + x = -4.358898944 + -7 x = -4.358898944 + -7 Combine like terms: -4.358898944 + -7 = -11.358898944 x = -11.358898944 Simplifying x = -11.358898944Solution
The solution to the problem is based on the solutions from the subproblems. x = {-2.641101056, -11.358898944}
