Simplifying 5x2 + -10x + -304 = 0 Reorder the terms: -304 + -10x + 5x2 = 0 Solving -304 + -10x + 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'. -60.8 + -2x + x2 = 0 Move the constant term to the right: Add '60.8' to each side of the equation. -60.8 + -2x + 60.8 + x2 = 0 + 60.8 Reorder the terms: -60.8 + 60.8 + -2x + x2 = 0 + 60.8 Combine like terms: -60.8 + 60.8 = 0.0 0.0 + -2x + x2 = 0 + 60.8 -2x + x2 = 0 + 60.8 Combine like terms: 0 + 60.8 = 60.8 -2x + x2 = 60.8 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 60.8 + 1 Reorder the terms: 1 + -2x + x2 = 60.8 + 1 Combine like terms: 60.8 + 1 = 61.8 1 + -2x + x2 = 61.8 Factor a perfect square on the left side: (x + -1)(x + -1) = 61.8 Calculate the square root of the right side: 7.861297603 Break this problem into two subproblems by setting (x + -1) equal to 7.861297603 and -7.861297603.Subproblem 1
x + -1 = 7.861297603 Simplifying x + -1 = 7.861297603 Reorder the terms: -1 + x = 7.861297603 Solving -1 + x = 7.861297603 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 7.861297603 + 1 Combine like terms: -1 + 1 = 0 0 + x = 7.861297603 + 1 x = 7.861297603 + 1 Combine like terms: 7.861297603 + 1 = 8.861297603 x = 8.861297603 Simplifying x = 8.861297603Subproblem 2
x + -1 = -7.861297603 Simplifying x + -1 = -7.861297603 Reorder the terms: -1 + x = -7.861297603 Solving -1 + x = -7.861297603 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -7.861297603 + 1 Combine like terms: -1 + 1 = 0 0 + x = -7.861297603 + 1 x = -7.861297603 + 1 Combine like terms: -7.861297603 + 1 = -6.861297603 x = -6.861297603 Simplifying x = -6.861297603Solution
