Simplifying 4x2 + 10x + -9 = 0 Reorder the terms: -9 + 10x + 4x2 = 0 Solving -9 + 10x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.25 + 2.5x + x2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + 2.5x + 2.25 + x2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + 2.5x + x2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + 2.5x + x2 = 0 + 2.25 2.5x + x2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 2.5x + x2 = 2.25 The x term is 2.5x. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x + 1.5625 + x2 = 2.25 + 1.5625 Reorder the terms: 1.5625 + 2.5x + x2 = 2.25 + 1.5625 Combine like terms: 2.25 + 1.5625 = 3.8125 1.5625 + 2.5x + x2 = 3.8125 Factor a perfect square on the left side: (x + 1.25)(x + 1.25) = 3.8125 Calculate the square root of the right side: 1.952562419 Break this problem into two subproblems by setting (x + 1.25) equal to 1.952562419 and -1.952562419.Subproblem 1
x + 1.25 = 1.952562419 Simplifying x + 1.25 = 1.952562419 Reorder the terms: 1.25 + x = 1.952562419 Solving 1.25 + x = 1.952562419 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = 1.952562419 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = 1.952562419 + -1.25 x = 1.952562419 + -1.25 Combine like terms: 1.952562419 + -1.25 = 0.702562419 x = 0.702562419 Simplifying x = 0.702562419Subproblem 2
x + 1.25 = -1.952562419 Simplifying x + 1.25 = -1.952562419 Reorder the terms: 1.25 + x = -1.952562419 Solving 1.25 + x = -1.952562419 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + x = -1.952562419 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + x = -1.952562419 + -1.25 x = -1.952562419 + -1.25 Combine like terms: -1.952562419 + -1.25 = -3.202562419 x = -3.202562419 Simplifying x = -3.202562419Solution
