Simplifying 2x2 + -7x + -13 = 0 Reorder the terms: -13 + -7x + 2x2 = 0 Solving -13 + -7x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -6.5 + -3.5x + x2 = 0 Move the constant term to the right: Add '6.5' to each side of the equation. -6.5 + -3.5x + 6.5 + x2 = 0 + 6.5 Reorder the terms: -6.5 + 6.5 + -3.5x + x2 = 0 + 6.5 Combine like terms: -6.5 + 6.5 = 0.0 0.0 + -3.5x + x2 = 0 + 6.5 -3.5x + x2 = 0 + 6.5 Combine like terms: 0 + 6.5 = 6.5 -3.5x + x2 = 6.5 The x term is -3.5x. Take half its coefficient (-1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. -3.5x + 3.0625 + x2 = 6.5 + 3.0625 Reorder the terms: 3.0625 + -3.5x + x2 = 6.5 + 3.0625 Combine like terms: 6.5 + 3.0625 = 9.5625 3.0625 + -3.5x + x2 = 9.5625 Factor a perfect square on the left side: (x + -1.75)(x + -1.75) = 9.5625 Calculate the square root of the right side: 3.092329219 Break this problem into two subproblems by setting (x + -1.75) equal to 3.092329219 and -3.092329219.Subproblem 1
x + -1.75 = 3.092329219 Simplifying x + -1.75 = 3.092329219 Reorder the terms: -1.75 + x = 3.092329219 Solving -1.75 + x = 3.092329219 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + x = 3.092329219 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + x = 3.092329219 + 1.75 x = 3.092329219 + 1.75 Combine like terms: 3.092329219 + 1.75 = 4.842329219 x = 4.842329219 Simplifying x = 4.842329219Subproblem 2
x + -1.75 = -3.092329219 Simplifying x + -1.75 = -3.092329219 Reorder the terms: -1.75 + x = -3.092329219 Solving -1.75 + x = -3.092329219 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.75' to each side of the equation. -1.75 + 1.75 + x = -3.092329219 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + x = -3.092329219 + 1.75 x = -3.092329219 + 1.75 Combine like terms: -3.092329219 + 1.75 = -1.342329219 x = -1.342329219 Simplifying x = -1.342329219Solution
