Simplifying 2x2 + 15x = 7 Reorder the terms: 15x + 2x2 = 7 Solving 15x + 2x2 = 7 Solving for variable 'x'. Reorder the terms: -7 + 15x + 2x2 = 7 + -7 Combine like terms: 7 + -7 = 0 -7 + 15x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -3.5 + 7.5x + x2 = 0 Move the constant term to the right: Add '3.5' to each side of the equation. -3.5 + 7.5x + 3.5 + x2 = 0 + 3.5 Reorder the terms: -3.5 + 3.5 + 7.5x + x2 = 0 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + 7.5x + x2 = 0 + 3.5 7.5x + x2 = 0 + 3.5 Combine like terms: 0 + 3.5 = 3.5 7.5x + x2 = 3.5 The x term is 7.5x. Take half its coefficient (3.75). Square it (14.0625) and add it to both sides. Add '14.0625' to each side of the equation. 7.5x + 14.0625 + x2 = 3.5 + 14.0625 Reorder the terms: 14.0625 + 7.5x + x2 = 3.5 + 14.0625 Combine like terms: 3.5 + 14.0625 = 17.5625 14.0625 + 7.5x + x2 = 17.5625 Factor a perfect square on the left side: (x + 3.75)(x + 3.75) = 17.5625 Calculate the square root of the right side: 4.190763654 Break this problem into two subproblems by setting (x + 3.75) equal to 4.190763654 and -4.190763654.Subproblem 1
x + 3.75 = 4.190763654 Simplifying x + 3.75 = 4.190763654 Reorder the terms: 3.75 + x = 4.190763654 Solving 3.75 + x = 4.190763654 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + x = 4.190763654 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + x = 4.190763654 + -3.75 x = 4.190763654 + -3.75 Combine like terms: 4.190763654 + -3.75 = 0.440763654 x = 0.440763654 Simplifying x = 0.440763654Subproblem 2
x + 3.75 = -4.190763654 Simplifying x + 3.75 = -4.190763654 Reorder the terms: 3.75 + x = -4.190763654 Solving 3.75 + x = -4.190763654 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.75' to each side of the equation. 3.75 + -3.75 + x = -4.190763654 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + x = -4.190763654 + -3.75 x = -4.190763654 + -3.75 Combine like terms: -4.190763654 + -3.75 = -7.940763654 x = -7.940763654 Simplifying x = -7.940763654Solution
