Simplifying 5x * x + -30x + 8 = 0 Multiply x * x 5x2 + -30x + 8 = 0 Reorder the terms: 8 + -30x + 5x2 = 0 Solving 8 + -30x + 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'. 1.6 + -6x + x2 = 0 Move the constant term to the right: Add '-1.6' to each side of the equation. 1.6 + -6x + -1.6 + x2 = 0 + -1.6 Reorder the terms: 1.6 + -1.6 + -6x + x2 = 0 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + -6x + x2 = 0 + -1.6 -6x + x2 = 0 + -1.6 Combine like terms: 0 + -1.6 = -1.6 -6x + x2 = -1.6 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -1.6 + 9 Reorder the terms: 9 + -6x + x2 = -1.6 + 9 Combine like terms: -1.6 + 9 = 7.4 9 + -6x + x2 = 7.4 Factor a perfect square on the left side: (x + -3)(x + -3) = 7.4 Calculate the square root of the right side: 2.720294102 Break this problem into two subproblems by setting (x + -3) equal to 2.720294102 and -2.720294102.Subproblem 1
x + -3 = 2.720294102 Simplifying x + -3 = 2.720294102 Reorder the terms: -3 + x = 2.720294102 Solving -3 + x = 2.720294102 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 2.720294102 + 3 Combine like terms: -3 + 3 = 0 0 + x = 2.720294102 + 3 x = 2.720294102 + 3 Combine like terms: 2.720294102 + 3 = 5.720294102 x = 5.720294102 Simplifying x = 5.720294102Subproblem 2
x + -3 = -2.720294102 Simplifying x + -3 = -2.720294102 Reorder the terms: -3 + x = -2.720294102 Solving -3 + x = -2.720294102 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = -2.720294102 + 3 Combine like terms: -3 + 3 = 0 0 + x = -2.720294102 + 3 x = -2.720294102 + 3 Combine like terms: -2.720294102 + 3 = 0.279705898 x = 0.279705898 Simplifying x = 0.279705898Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.720294102, 0.279705898}
