Simplifying 144 = 5x2 + -8x + 11 Reorder the terms: 144 = 11 + -8x + 5x2 Solving 144 = 11 + -8x + 5x2 Solving for variable 'x'. Combine like terms: 144 + -11 = 133 133 + 8x + -5x2 = 11 + -8x + 5x2 + -11 + 8x + -5x2 Reorder the terms: 133 + 8x + -5x2 = 11 + -11 + -8x + 8x + 5x2 + -5x2 Combine like terms: 11 + -11 = 0 133 + 8x + -5x2 = 0 + -8x + 8x + 5x2 + -5x2 133 + 8x + -5x2 = -8x + 8x + 5x2 + -5x2 Combine like terms: -8x + 8x = 0 133 + 8x + -5x2 = 0 + 5x2 + -5x2 133 + 8x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 133 + 8x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -26.6 + -1.6x + x2 = 0 Move the constant term to the right: Add '26.6' to each side of the equation. -26.6 + -1.6x + 26.6 + x2 = 0 + 26.6 Reorder the terms: -26.6 + 26.6 + -1.6x + x2 = 0 + 26.6 Combine like terms: -26.6 + 26.6 = 0.0 0.0 + -1.6x + x2 = 0 + 26.6 -1.6x + x2 = 0 + 26.6 Combine like terms: 0 + 26.6 = 26.6 -1.6x + x2 = 26.6 The x term is -1.6x. Take half its coefficient (-0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. -1.6x + 0.64 + x2 = 26.6 + 0.64 Reorder the terms: 0.64 + -1.6x + x2 = 26.6 + 0.64 Combine like terms: 26.6 + 0.64 = 27.24 0.64 + -1.6x + x2 = 27.24 Factor a perfect square on the left side: (x + -0.8)(x + -0.8) = 27.24 Calculate the square root of the right side: 5.21919534 Break this problem into two subproblems by setting (x + -0.8) equal to 5.21919534 and -5.21919534.Subproblem 1
x + -0.8 = 5.21919534 Simplifying x + -0.8 = 5.21919534 Reorder the terms: -0.8 + x = 5.21919534 Solving -0.8 + x = 5.21919534 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = 5.21919534 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = 5.21919534 + 0.8 x = 5.21919534 + 0.8 Combine like terms: 5.21919534 + 0.8 = 6.01919534 x = 6.01919534 Simplifying x = 6.01919534Subproblem 2
x + -0.8 = -5.21919534 Simplifying x + -0.8 = -5.21919534 Reorder the terms: -0.8 + x = -5.21919534 Solving -0.8 + x = -5.21919534 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.8' to each side of the equation. -0.8 + 0.8 + x = -5.21919534 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + x = -5.21919534 + 0.8 x = -5.21919534 + 0.8 Combine like terms: -5.21919534 + 0.8 = -4.41919534 x = -4.41919534 Simplifying x = -4.41919534Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.01919534, -4.41919534}
