Simplifying 3x2 + 15x + 13 = 0 Reorder the terms: 13 + 15x + 3x2 = 0 Solving 13 + 15x + 3x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 4.333333333 + 5x + x2 = 0 Move the constant term to the right: Add '-4.333333333' to each side of the equation. 4.333333333 + 5x + -4.333333333 + x2 = 0 + -4.333333333 Reorder the terms: 4.333333333 + -4.333333333 + 5x + x2 = 0 + -4.333333333 Combine like terms: 4.333333333 + -4.333333333 = 0.000000000 0.000000000 + 5x + x2 = 0 + -4.333333333 5x + x2 = 0 + -4.333333333 Combine like terms: 0 + -4.333333333 = -4.333333333 5x + x2 = -4.333333333 The x term is 5x. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5x + 6.25 + x2 = -4.333333333 + 6.25 Reorder the terms: 6.25 + 5x + x2 = -4.333333333 + 6.25 Combine like terms: -4.333333333 + 6.25 = 1.916666667 6.25 + 5x + x2 = 1.916666667 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 1.916666667 Calculate the square root of the right side: 1.384437311 Break this problem into two subproblems by setting (x + 2.5) equal to 1.384437311 and -1.384437311.Subproblem 1
x + 2.5 = 1.384437311 Simplifying x + 2.5 = 1.384437311 Reorder the terms: 2.5 + x = 1.384437311 Solving 2.5 + x = 1.384437311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = 1.384437311 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 1.384437311 + -2.5 x = 1.384437311 + -2.5 Combine like terms: 1.384437311 + -2.5 = -1.115562689 x = -1.115562689 Simplifying x = -1.115562689Subproblem 2
x + 2.5 = -1.384437311 Simplifying x + 2.5 = -1.384437311 Reorder the terms: 2.5 + x = -1.384437311 Solving 2.5 + x = -1.384437311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + x = -1.384437311 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -1.384437311 + -2.5 x = -1.384437311 + -2.5 Combine like terms: -1.384437311 + -2.5 = -3.884437311 x = -3.884437311 Simplifying x = -3.884437311Solution
