Simplifying -16x2 + 40x + 3 = 0 Reorder the terms: 3 + 40x + -16x2 = 0 Solving 3 + 40x + -16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. -0.1875 + -2.5x + x2 = 0 Move the constant term to the right: Add '0.1875' to each side of the equation. -0.1875 + -2.5x + 0.1875 + x2 = 0 + 0.1875 Reorder the terms: -0.1875 + 0.1875 + -2.5x + x2 = 0 + 0.1875 Combine like terms: -0.1875 + 0.1875 = 0.0000 0.0000 + -2.5x + x2 = 0 + 0.1875 -2.5x + x2 = 0 + 0.1875 Combine like terms: 0 + 0.1875 = 0.1875 -2.5x + x2 = 0.1875 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 = 0.1875 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 0.1875 + 1.5625 Combine like terms: 0.1875 + 1.5625 = 1.75 1.5625 + -2.5x + x2 = 1.75 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 1.75 Calculate the square root of the right side: 1.322875656 Break this problem into two subproblems by setting (x + -1.25) equal to 1.322875656 and -1.322875656.Subproblem 1
x + -1.25 = 1.322875656 Simplifying x + -1.25 = 1.322875656 Reorder the terms: -1.25 + x = 1.322875656 Solving -1.25 + x = 1.322875656 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 = 1.322875656 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 1.322875656 + 1.25 x = 1.322875656 + 1.25 Combine like terms: 1.322875656 + 1.25 = 2.572875656 x = 2.572875656 Simplifying x = 2.572875656Subproblem 2
x + -1.25 = -1.322875656 Simplifying x + -1.25 = -1.322875656 Reorder the terms: -1.25 + x = -1.322875656 Solving -1.25 + x = -1.322875656 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 = -1.322875656 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -1.322875656 + 1.25 x = -1.322875656 + 1.25 Combine like terms: -1.322875656 + 1.25 = -0.072875656 x = -0.072875656 Simplifying x = -0.072875656Solution
