Simplifying 16x2 + -1(-20x) = 4x + -1(-9) Remove parenthesis around (-20x) 16x2 + -1 * -20x = 4x + -1(-9) Multiply -1 * -20 16x2 + 20x = 4x + -1(-9) Reorder the terms: 20x + 16x2 = 4x + -1(-9) Multiply -1 * -9 20x + 16x2 = 4x + 9 Reorder the terms: 20x + 16x2 = 9 + 4x Solving 20x + 16x2 = 9 + 4x Solving for variable 'x'. Reorder the terms: -9 + 20x + -4x + 16x2 = 9 + 4x + -9 + -4x Combine like terms: 20x + -4x = 16x -9 + 16x + 16x2 = 9 + 4x + -9 + -4x Reorder the terms: -9 + 16x + 16x2 = 9 + -9 + 4x + -4x Combine like terms: 9 + -9 = 0 -9 + 16x + 16x2 = 0 + 4x + -4x -9 + 16x + 16x2 = 4x + -4x Combine like terms: 4x + -4x = 0 -9 + 16x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.5625 + x + x2 = 0 Move the constant term to the right: Add '0.5625' to each side of the equation. -0.5625 + x + 0.5625 + x2 = 0 + 0.5625 Reorder the terms: -0.5625 + 0.5625 + x + x2 = 0 + 0.5625 Combine like terms: -0.5625 + 0.5625 = 0.0000 0.0000 + x + x2 = 0 + 0.5625 x + x2 = 0 + 0.5625 Combine like terms: 0 + 0.5625 = 0.5625 x + x2 = 0.5625 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + x2 = 0.5625 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 0.5625 + 0.25 Combine like terms: 0.5625 + 0.25 = 0.8125 1.25 + x2 = 0.8125 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.8125 Calculate the square root of the right side: 0.901387819 Break this problem into two subproblems by setting (x + 0.5) equal to 0.901387819 and -0.901387819.Subproblem 1
x + 0.5 = 0.901387819 Simplifying x + 0.5 = 0.901387819 Reorder the terms: 0.5 + x = 0.901387819 Solving 0.5 + x = 0.901387819 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 0.901387819 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.901387819 + -0.5 x = 0.901387819 + -0.5 Combine like terms: 0.901387819 + -0.5 = 0.401387819 x = 0.401387819 Simplifying x = 0.401387819Subproblem 2
x + 0.5 = -0.901387819 Simplifying x + 0.5 = -0.901387819 Reorder the terms: 0.5 + x = -0.901387819 Solving 0.5 + x = -0.901387819 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -0.901387819 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -0.901387819 + -0.5 x = -0.901387819 + -0.5 Combine like terms: -0.901387819 + -0.5 = -1.401387819 x = -1.401387819 Simplifying x = -1.401387819Solution
