Simplifying 36x = -4x2 + -50 Reorder the terms: 36x = -50 + -4x2 Solving 36x = -50 + -4x2 Solving for variable 'x'. Reorder the terms: 50 + 36x + 4x2 = -50 + -4x2 + 50 + 4x2 Reorder the terms: 50 + 36x + 4x2 = -50 + 50 + -4x2 + 4x2 Combine like terms: -50 + 50 = 0 50 + 36x + 4x2 = 0 + -4x2 + 4x2 50 + 36x + 4x2 = -4x2 + 4x2 Combine like terms: -4x2 + 4x2 = 0 50 + 36x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(25 + 18x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(25 + 18x + 2x2)' equal to zero and attempt to solve: Simplifying 25 + 18x + 2x2 = 0 Solving 25 + 18x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 12.5 + 9x + x2 = 0 Move the constant term to the right: Add '-12.5' to each side of the equation. 12.5 + 9x + -12.5 + x2 = 0 + -12.5 Reorder the terms: 12.5 + -12.5 + 9x + x2 = 0 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + 9x + x2 = 0 + -12.5 9x + x2 = 0 + -12.5 Combine like terms: 0 + -12.5 = -12.5 9x + x2 = -12.5 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = -12.5 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -12.5 + 20.25 Combine like terms: -12.5 + 20.25 = 7.75 20.25 + 9x + x2 = 7.75 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 7.75 Calculate the square root of the right side: 2.783882181 Break this problem into two subproblems by setting (x + 4.5) equal to 2.783882181 and -2.783882181.Subproblem 1
x + 4.5 = 2.783882181 Simplifying x + 4.5 = 2.783882181 Reorder the terms: 4.5 + x = 2.783882181 Solving 4.5 + x = 2.783882181 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 2.783882181 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 2.783882181 + -4.5 x = 2.783882181 + -4.5 Combine like terms: 2.783882181 + -4.5 = -1.716117819 x = -1.716117819 Simplifying x = -1.716117819Subproblem 2
x + 4.5 = -2.783882181 Simplifying x + 4.5 = -2.783882181 Reorder the terms: 4.5 + x = -2.783882181 Solving 4.5 + x = -2.783882181 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -2.783882181 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -2.783882181 + -4.5 x = -2.783882181 + -4.5 Combine like terms: -2.783882181 + -4.5 = -7.283882181 x = -7.283882181 Simplifying x = -7.283882181Solution
