Simplifying (2x2 + -3x + -56) + (6x2 + 9x) = 0 Reorder the terms: (-56 + -3x + 2x2) + (6x2 + 9x) = 0 Remove parenthesis around (-56 + -3x + 2x2) -56 + -3x + 2x2 + (6x2 + 9x) = 0 Reorder the terms: -56 + -3x + 2x2 + (9x + 6x2) = 0 Remove parenthesis around (9x + 6x2) -56 + -3x + 2x2 + 9x + 6x2 = 0 Reorder the terms: -56 + -3x + 9x + 2x2 + 6x2 = 0 Combine like terms: -3x + 9x = 6x -56 + 6x + 2x2 + 6x2 = 0 Combine like terms: 2x2 + 6x2 = 8x2 -56 + 6x + 8x2 = 0 Solving -56 + 6x + 8x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-28 + 3x + 4x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-28 + 3x + 4x2)' equal to zero and attempt to solve: Simplifying -28 + 3x + 4x2 = 0 Solving -28 + 3x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -7 + 0.75x + x2 = 0 Move the constant term to the right: Add '7' to each side of the equation. -7 + 0.75x + 7 + x2 = 0 + 7 Reorder the terms: -7 + 7 + 0.75x + x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 0.75x + x2 = 0 + 7 0.75x + x2 = 0 + 7 Combine like terms: 0 + 7 = 7 0.75x + x2 = 7 The x term is 0.75x. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75x + 0.140625 + x2 = 7 + 0.140625 Reorder the terms: 0.140625 + 0.75x + x2 = 7 + 0.140625 Combine like terms: 7 + 0.140625 = 7.140625 0.140625 + 0.75x + x2 = 7.140625 Factor a perfect square on the left side: (x + 0.375)(x + 0.375) = 7.140625 Calculate the square root of the right side: 2.672194791 Break this problem into two subproblems by setting (x + 0.375) equal to 2.672194791 and -2.672194791.Subproblem 1
x + 0.375 = 2.672194791 Simplifying x + 0.375 = 2.672194791 Reorder the terms: 0.375 + x = 2.672194791 Solving 0.375 + x = 2.672194791 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + x = 2.672194791 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + x = 2.672194791 + -0.375 x = 2.672194791 + -0.375 Combine like terms: 2.672194791 + -0.375 = 2.297194791 x = 2.297194791 Simplifying x = 2.297194791Subproblem 2
x + 0.375 = -2.672194791 Simplifying x + 0.375 = -2.672194791 Reorder the terms: 0.375 + x = -2.672194791 Solving 0.375 + x = -2.672194791 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
