Simplifying -4x2 + 9x + 7 = 0 Reorder the terms: 7 + 9x + -4x2 = 0 Solving 7 + 9x + -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'. -1.75 + -2.25x + x2 = 0 Move the constant term to the right: Add '1.75' to each side of the equation. -1.75 + -2.25x + 1.75 + x2 = 0 + 1.75 Reorder the terms: -1.75 + 1.75 + -2.25x + x2 = 0 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + -2.25x + x2 = 0 + 1.75 -2.25x + x2 = 0 + 1.75 Combine like terms: 0 + 1.75 = 1.75 -2.25x + x2 = 1.75 The x term is -2.25x. Take half its coefficient (-1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. -2.25x + 1.265625 + x2 = 1.75 + 1.265625 Reorder the terms: 1.265625 + -2.25x + x2 = 1.75 + 1.265625 Combine like terms: 1.75 + 1.265625 = 3.015625 1.265625 + -2.25x + x2 = 3.015625 Factor a perfect square on the left side: (x + -1.125)(x + -1.125) = 3.015625 Calculate the square root of the right side: 1.736555499 Break this problem into two subproblems by setting (x + -1.125) equal to 1.736555499 and -1.736555499.Subproblem 1
x + -1.125 = 1.736555499 Simplifying x + -1.125 = 1.736555499 Reorder the terms: -1.125 + x = 1.736555499 Solving -1.125 + x = 1.736555499 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + x = 1.736555499 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + x = 1.736555499 + 1.125 x = 1.736555499 + 1.125 Combine like terms: 1.736555499 + 1.125 = 2.861555499 x = 2.861555499 Simplifying x = 2.861555499Subproblem 2
x + -1.125 = -1.736555499 Simplifying x + -1.125 = -1.736555499 Reorder the terms: -1.125 + x = -1.736555499 Solving -1.125 + x = -1.736555499 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.125' to each side of the equation. -1.125 + 1.125 + x = -1.736555499 + 1.125 Combine like terms: -1.125 + 1.125 = 0.000 0.000 + x = -1.736555499 + 1.125 x = -1.736555499 + 1.125 Combine like terms: -1.736555499 + 1.125 = -0.611555499 x = -0.611555499 Simplifying x = -0.611555499Solution
