Simplifying 5x2 + -40x + 6 = 0 Reorder the terms: 6 + -40x + 5x2 = 0 Solving 6 + -40x + 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'. 1.2 + -8x + x2 = 0 Move the constant term to the right: Add '-1.2' to each side of the equation. 1.2 + -8x + -1.2 + x2 = 0 + -1.2 Reorder the terms: 1.2 + -1.2 + -8x + x2 = 0 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + -8x + x2 = 0 + -1.2 -8x + x2 = 0 + -1.2 Combine like terms: 0 + -1.2 = -1.2 -8x + x2 = -1.2 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = -1.2 + 16 Reorder the terms: 16 + -8x + x2 = -1.2 + 16 Combine like terms: -1.2 + 16 = 14.8 16 + -8x + x2 = 14.8 Factor a perfect square on the left side: (x + -4)(x + -4) = 14.8 Calculate the square root of the right side: 3.847076812 Break this problem into two subproblems by setting (x + -4) equal to 3.847076812 and -3.847076812.Subproblem 1
x + -4 = 3.847076812 Simplifying x + -4 = 3.847076812 Reorder the terms: -4 + x = 3.847076812 Solving -4 + x = 3.847076812 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 3.847076812 + 4 Combine like terms: -4 + 4 = 0 0 + x = 3.847076812 + 4 x = 3.847076812 + 4 Combine like terms: 3.847076812 + 4 = 7.847076812 x = 7.847076812 Simplifying x = 7.847076812Subproblem 2
x + -4 = -3.847076812 Simplifying x + -4 = -3.847076812 Reorder the terms: -4 + x = -3.847076812 Solving -4 + x = -3.847076812 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = -3.847076812 + 4 Combine like terms: -4 + 4 = 0 0 + x = -3.847076812 + 4 x = -3.847076812 + 4 Combine like terms: -3.847076812 + 4 = 0.152923188 x = 0.152923188 Simplifying x = 0.152923188Solution
