Set the factor '(1250 + 12x + -15x2)' equal to zero and attempt to solve: Simplifying 1250 + 12x + -15x2 = 0 Solving 1250 + 12x + -15x2 = 0 Begin completing the square. Divide all terms by -15 the coefficient of the squared term: Divide each side by '-15'. -83.33333333 + -0.8x + x2 = 0 Move the constant term to the right: Add '83.33333333' to each side of the equation. -83.33333333 + -0.8x + 83.33333333 + x2 = 0 + 83.33333333 Reorder the terms: -83.33333333 + 83.33333333 + -0.8x + x2 = 0 + 83.33333333 Combine like terms: -83.33333333 + 83.33333333 = 0.00000000 0.00000000 + -0.8x + x2 = 0 + 83.33333333 -0.8x + x2 = 0 + 83.33333333 Combine like terms: 0 + 83.33333333 = 83.33333333 -0.8x + x2 = 83.33333333 The x term is -0.8x. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8x + 0.16 + x2 = 83.33333333 + 0.16 Reorder the terms: 0.16 + -0.8x + x2 = 83.33333333 + 0.16 Combine like terms: 83.33333333 + 0.16 = 83.49333333 0.16 + -0.8x + x2 = 83.49333333 Factor a perfect square on the left side: (x + -0.4)(x + -0.4) = 83.49333333 Calculate the square root of the right side: 9.13746865 Break this problem into two subproblems by setting (x + -0.4) equal to 9.13746865 and -9.13746865.Subproblem 1
x + -0.4 = 9.13746865 Simplifying x + -0.4 = 9.13746865 Reorder the terms: -0.4 + x = 9.13746865 Solving -0.4 + x = 9.13746865 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + x = 9.13746865 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = 9.13746865 + 0.4 x = 9.13746865 + 0.4 Combine like terms: 9.13746865 + 0.4 = 9.53746865 x = 9.53746865 Simplifying x = 9.53746865Subproblem 2
