Simplifying 5x2 + -40x = 90 Reorder the terms: -40x + 5x2 = 90 Solving -40x + 5x2 = 90 Solving for variable 'x'. Reorder the terms: -90 + -40x + 5x2 = 90 + -90 Combine like terms: 90 + -90 = 0 -90 + -40x + 5x2 = 0 Factor out the Greatest Common Factor (GCF), '5'. 5(-18 + -8x + x2) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(-18 + -8x + x2)' equal to zero and attempt to solve: Simplifying -18 + -8x + x2 = 0 Solving -18 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '18' to each side of the equation. -18 + -8x + 18 + x2 = 0 + 18 Reorder the terms: -18 + 18 + -8x + x2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + -8x + x2 = 0 + 18 -8x + x2 = 0 + 18 Combine like terms: 0 + 18 = 18 -8x + x2 = 18 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = 18 + 16 Reorder the terms: 16 + -8x + x2 = 18 + 16 Combine like terms: 18 + 16 = 34 16 + -8x + x2 = 34 Factor a perfect square on the left side: (x + -4)(x + -4) = 34 Calculate the square root of the right side: 5.830951895 Break this problem into two subproblems by setting (x + -4) equal to 5.830951895 and -5.830951895.Subproblem 1
x + -4 = 5.830951895 Simplifying x + -4 = 5.830951895 Reorder the terms: -4 + x = 5.830951895 Solving -4 + x = 5.830951895 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 5.830951895 + 4 Combine like terms: -4 + 4 = 0 0 + x = 5.830951895 + 4 x = 5.830951895 + 4 Combine like terms: 5.830951895 + 4 = 9.830951895 x = 9.830951895 Simplifying x = 9.830951895Subproblem 2
x + -4 = -5.830951895 Simplifying x + -4 = -5.830951895 Reorder the terms: -4 + x = -5.830951895 Solving -4 + x = -5.830951895 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = -5.830951895 + 4 Combine like terms: -4 + 4 = 0 0 + x = -5.830951895 + 4 x = -5.830951895 + 4 Combine like terms: -5.830951895 + 4 = -1.830951895 x = -1.830951895 Simplifying x = -1.830951895Solution
