Simplifying 5x2 + -4x + -76 = 0 Reorder the terms: -76 + -4x + 5x2 = 0 Solving -76 + -4x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -15.2 + -0.8x + x2 = 0 Move the constant term to the right: Add '15.2' to each side of the equation. -15.2 + -0.8x + 15.2 + x2 = 0 + 15.2 Reorder the terms: -15.2 + 15.2 + -0.8x + x2 = 0 + 15.2 Combine like terms: -15.2 + 15.2 = 0.0 0.0 + -0.8x + x2 = 0 + 15.2 -0.8x + x2 = 0 + 15.2 Combine like terms: 0 + 15.2 = 15.2 -0.8x + x2 = 15.2 The x term is -0.8x. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8x + 0.16 + x2 = 15.2 + 0.16 Reorder the terms: 0.16 + -0.8x + x2 = 15.2 + 0.16 Combine like terms: 15.2 + 0.16 = 15.36 0.16 + -0.8x + x2 = 15.36 Factor a perfect square on the left side: (x + -0.4)(x + -0.4) = 15.36 Calculate the square root of the right side: 3.919183588 Break this problem into two subproblems by setting (x + -0.4) equal to 3.919183588 and -3.919183588.Subproblem 1
x + -0.4 = 3.919183588 Simplifying x + -0.4 = 3.919183588 Reorder the terms: -0.4 + x = 3.919183588 Solving -0.4 + x = 3.919183588 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + x = 3.919183588 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = 3.919183588 + 0.4 x = 3.919183588 + 0.4 Combine like terms: 3.919183588 + 0.4 = 4.319183588 x = 4.319183588 Simplifying x = 4.319183588Subproblem 2
x + -0.4 = -3.919183588 Simplifying x + -0.4 = -3.919183588 Reorder the terms: -0.4 + x = -3.919183588 Solving -0.4 + x = -3.919183588 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + x = -3.919183588 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = -3.919183588 + 0.4 x = -3.919183588 + 0.4 Combine like terms: -3.919183588 + 0.4 = -3.519183588 x = -3.519183588 Simplifying x = -3.519183588Solution
