Simplifying -13 = 9x + -2x2 Solving -13 = 9x + -2x2 Solving for variable 'x'. Reorder the terms: -13 + -9x + 2x2 = 9x + -9x + -2x2 + 2x2 Combine like terms: 9x + -9x = 0 -13 + -9x + 2x2 = 0 + -2x2 + 2x2 -13 + -9x + 2x2 = -2x2 + 2x2 Combine like terms: -2x2 + 2x2 = 0 -13 + -9x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -6.5 + -4.5x + x2 = 0 Move the constant term to the right: Add '6.5' to each side of the equation. -6.5 + -4.5x + 6.5 + x2 = 0 + 6.5 Reorder the terms: -6.5 + 6.5 + -4.5x + x2 = 0 + 6.5 Combine like terms: -6.5 + 6.5 = 0.0 0.0 + -4.5x + x2 = 0 + 6.5 -4.5x + x2 = 0 + 6.5 Combine like terms: 0 + 6.5 = 6.5 -4.5x + x2 = 6.5 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = 6.5 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = 6.5 + 5.0625 Combine like terms: 6.5 + 5.0625 = 11.5625 5.0625 + -4.5x + x2 = 11.5625 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = 11.5625 Calculate the square root of the right side: 3.400367627 Break this problem into two subproblems by setting (x + -2.25) equal to 3.400367627 and -3.400367627.Subproblem 1
x + -2.25 = 3.400367627 Simplifying x + -2.25 = 3.400367627 Reorder the terms: -2.25 + x = 3.400367627 Solving -2.25 + x = 3.400367627 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + x = 3.400367627 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + x = 3.400367627 + 2.25 x = 3.400367627 + 2.25 Combine like terms: 3.400367627 + 2.25 = 5.650367627 x = 5.650367627 Simplifying x = 5.650367627Subproblem 2
x + -2.25 = -3.400367627 Simplifying x + -2.25 = -3.400367627 Reorder the terms: -2.25 + x = -3.400367627 Solving -2.25 + x = -3.400367627 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + x = -3.400367627 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + x = -3.400367627 + 2.25 x = -3.400367627 + 2.25 Combine like terms: -3.400367627 + 2.25 = -1.150367627 x = -1.150367627 Simplifying x = -1.150367627Solution
