Simplifying 2x2 + 7x + -20 = 0 Reorder the terms: -20 + 7x + 2x2 = 0 Solving -20 + 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'. -10 + 3.5x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + 3.5x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + 3.5x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + 3.5x + x2 = 0 + 10 3.5x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 3.5x + x2 = 10 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 = 10 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = 10 + 3.0625 Combine like terms: 10 + 3.0625 = 13.0625 3.0625 + 3.5x + x2 = 13.0625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 13.0625 Calculate the square root of the right side: 3.614208074 Break this problem into two subproblems by setting (x + 1.75) equal to 3.614208074 and -3.614208074.Subproblem 1
x + 1.75 = 3.614208074 Simplifying x + 1.75 = 3.614208074 Reorder the terms: 1.75 + x = 3.614208074 Solving 1.75 + x = 3.614208074 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 = 3.614208074 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 3.614208074 + -1.75 x = 3.614208074 + -1.75 Combine like terms: 3.614208074 + -1.75 = 1.864208074 x = 1.864208074 Simplifying x = 1.864208074Subproblem 2
x + 1.75 = -3.614208074 Simplifying x + 1.75 = -3.614208074 Reorder the terms: 1.75 + x = -3.614208074 Solving 1.75 + x = -3.614208074 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 = -3.614208074 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -3.614208074 + -1.75 x = -3.614208074 + -1.75 Combine like terms: -3.614208074 + -1.75 = -5.364208074 x = -5.364208074 Simplifying x = -5.364208074Solution
