Simplifying -2x2 + 25x + -15 = 0 Reorder the terms: -15 + 25x + -2x2 = 0 Solving -15 + 25x + -2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 7.5 + -12.5x + x2 = 0 Move the constant term to the right: Add '-7.5' to each side of the equation. 7.5 + -12.5x + -7.5 + x2 = 0 + -7.5 Reorder the terms: 7.5 + -7.5 + -12.5x + x2 = 0 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + -12.5x + x2 = 0 + -7.5 -12.5x + x2 = 0 + -7.5 Combine like terms: 0 + -7.5 = -7.5 -12.5x + x2 = -7.5 The x term is -12.5x. Take half its coefficient (-6.25). Square it (39.0625) and add it to both sides. Add '39.0625' to each side of the equation. -12.5x + 39.0625 + x2 = -7.5 + 39.0625 Reorder the terms: 39.0625 + -12.5x + x2 = -7.5 + 39.0625 Combine like terms: -7.5 + 39.0625 = 31.5625 39.0625 + -12.5x + x2 = 31.5625 Factor a perfect square on the left side: (x + -6.25)(x + -6.25) = 31.5625 Calculate the square root of the right side: 5.618051264 Break this problem into two subproblems by setting (x + -6.25) equal to 5.618051264 and -5.618051264.Subproblem 1
x + -6.25 = 5.618051264 Simplifying x + -6.25 = 5.618051264 Reorder the terms: -6.25 + x = 5.618051264 Solving -6.25 + x = 5.618051264 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.25' to each side of the equation. -6.25 + 6.25 + x = 5.618051264 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + x = 5.618051264 + 6.25 x = 5.618051264 + 6.25 Combine like terms: 5.618051264 + 6.25 = 11.868051264 x = 11.868051264 Simplifying x = 11.868051264Subproblem 2
x + -6.25 = -5.618051264 Simplifying x + -6.25 = -5.618051264 Reorder the terms: -6.25 + x = -5.618051264 Solving -6.25 + x = -5.618051264 Solving for variable 'x'.
