Simplifying (5x2 + 5x + -3) + (-9x2 + 8) = 0 Reorder the terms: (-3 + 5x + 5x2) + (-9x2 + 8) = 0 Remove parenthesis around (-3 + 5x + 5x2) -3 + 5x + 5x2 + (-9x2 + 8) = 0 Reorder the terms: -3 + 5x + 5x2 + (8 + -9x2) = 0 Remove parenthesis around (8 + -9x2) -3 + 5x + 5x2 + 8 + -9x2 = 0 Reorder the terms: -3 + 8 + 5x + 5x2 + -9x2 = 0 Combine like terms: -3 + 8 = 5 5 + 5x + 5x2 + -9x2 = 0 Combine like terms: 5x2 + -9x2 = -4x2 5 + 5x + -4x2 = 0 Solving 5 + 5x + -4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -1.25 + -1.25x + x2 = 0 Move the constant term to the right: Add '1.25' to each side of the equation. -1.25 + -1.25x + 1.25 + x2 = 0 + 1.25 Reorder the terms: -1.25 + 1.25 + -1.25x + x2 = 0 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + -1.25x + x2 = 0 + 1.25 -1.25x + x2 = 0 + 1.25 Combine like terms: 0 + 1.25 = 1.25 -1.25x + x2 = 1.25 The x term is -1.25x. Take half its coefficient (-0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. -1.25x + 0.390625 + x2 = 1.25 + 0.390625 Reorder the terms: 0.390625 + -1.25x + x2 = 1.25 + 0.390625 Combine like terms: 1.25 + 0.390625 = 1.640625 0.390625 + -1.25x + x2 = 1.640625 Factor a perfect square on the left side: (x + -0.625)(x + -0.625) = 1.640625 Calculate the square root of the right side: 1.280868846 Break this problem into two subproblems by setting (x + -0.625) equal to 1.280868846 and -1.280868846.Subproblem 1
x + -0.625 = 1.280868846 Simplifying x + -0.625 = 1.280868846 Reorder the terms: -0.625 + x = 1.280868846 Solving -0.625 + x = 1.280868846 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = 1.280868846 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = 1.280868846 + 0.625 x = 1.280868846 + 0.625 Combine like terms: 1.280868846 + 0.625 = 1.905868846 x = 1.905868846 Simplifying x = 1.905868846Subproblem 2
x + -0.625 = -1.280868846 Simplifying x + -0.625 = -1.280868846 Reorder the terms: -0.625 + x = -1.280868846 Solving -0.625 + x = -1.280868846 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.625' to each side of the equation. -0.625 + 0.625 + x = -1.280868846 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + x = -1.280868846 + 0.625 x = -1.280868846 + 0.625 Combine like terms: -1.280868846 + 0.625 = -0.655868846 x = -0.655868846 Simplifying x = -0.655868846Solution
