Simplifying 4x2 + -56x + 128 = 0 Reorder the terms: 128 + -56x + 4x2 = 0 Solving 128 + -56x + 4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '4'. 4(32 + -14x + x2) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(32 + -14x + x2)' equal to zero and attempt to solve: Simplifying 32 + -14x + x2 = 0 Solving 32 + -14x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-32' to each side of the equation. 32 + -14x + -32 + x2 = 0 + -32 Reorder the terms: 32 + -32 + -14x + x2 = 0 + -32 Combine like terms: 32 + -32 = 0 0 + -14x + x2 = 0 + -32 -14x + x2 = 0 + -32 Combine like terms: 0 + -32 = -32 -14x + x2 = -32 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 = -32 + 49 Reorder the terms: 49 + -14x + x2 = -32 + 49 Combine like terms: -32 + 49 = 17 49 + -14x + x2 = 17 Factor a perfect square on the left side: (x + -7)(x + -7) = 17 Calculate the square root of the right side: 4.123105626 Break this problem into two subproblems by setting (x + -7) equal to 4.123105626 and -4.123105626.Subproblem 1
x + -7 = 4.123105626 Simplifying x + -7 = 4.123105626 Reorder the terms: -7 + x = 4.123105626 Solving -7 + x = 4.123105626 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 = 4.123105626 + 7 Combine like terms: -7 + 7 = 0 0 + x = 4.123105626 + 7 x = 4.123105626 + 7 Combine like terms: 4.123105626 + 7 = 11.123105626 x = 11.123105626 Simplifying x = 11.123105626Subproblem 2
x + -7 = -4.123105626 Simplifying x + -7 = -4.123105626 Reorder the terms: -7 + x = -4.123105626 Solving -7 + x = -4.123105626 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 = -4.123105626 + 7 Combine like terms: -7 + 7 = 0 0 + x = -4.123105626 + 7 x = -4.123105626 + 7 Combine like terms: -4.123105626 + 7 = 2.876894374 x = 2.876894374 Simplifying x = 2.876894374Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.123105626, 2.876894374}Solution
x = {11.123105626, 2.876894374}
