Simplifying 0 = x2 + 15x + 3 Reorder the terms: 0 = 3 + 15x + x2 Solving 0 = 3 + 15x + x2 Solving for variable 'x'. Combine like terms: 0 + -3 = -3 -3 + -15x + -1x2 = 3 + 15x + x2 + -3 + -15x + -1x2 Reorder the terms: -3 + -15x + -1x2 = 3 + -3 + 15x + -15x + x2 + -1x2 Combine like terms: 3 + -3 = 0 -3 + -15x + -1x2 = 0 + 15x + -15x + x2 + -1x2 -3 + -15x + -1x2 = 15x + -15x + x2 + -1x2 Combine like terms: 15x + -15x = 0 -3 + -15x + -1x2 = 0 + x2 + -1x2 -3 + -15x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -3 + -15x + -1x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(3 + 15x + x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(3 + 15x + x2)' equal to zero and attempt to solve: Simplifying 3 + 15x + x2 = 0 Solving 3 + 15x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 15x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + 15x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 15x + x2 = 0 + -3 15x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 15x + x2 = -3 The x term is 15x. Take half its coefficient (7.5). Square it (56.25) and add it to both sides. Add '56.25' to each side of the equation. 15x + 56.25 + x2 = -3 + 56.25 Reorder the terms: 56.25 + 15x + x2 = -3 + 56.25 Combine like terms: -3 + 56.25 = 53.25 56.25 + 15x + x2 = 53.25 Factor a perfect square on the left side: (x + 7.5)(x + 7.5) = 53.25 Calculate the square root of the right side: 7.29725976 Break this problem into two subproblems by setting (x + 7.5) equal to 7.29725976 and -7.29725976.Subproblem 1
x + 7.5 = 7.29725976 Simplifying x + 7.5 = 7.29725976 Reorder the terms: 7.5 + x = 7.29725976 Solving 7.5 + x = 7.29725976 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = 7.29725976 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = 7.29725976 + -7.5 x = 7.29725976 + -7.5 Combine like terms: 7.29725976 + -7.5 = -0.20274024 x = -0.20274024 Simplifying x = -0.20274024Subproblem 2
x + 7.5 = -7.29725976 Simplifying x + 7.5 = -7.29725976 Reorder the terms: 7.5 + x = -7.29725976 Solving 7.5 + x = -7.29725976 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7.5' to each side of the equation. 7.5 + -7.5 + x = -7.29725976 + -7.5 Combine like terms: 7.5 + -7.5 = 0.0 0.0 + x = -7.29725976 + -7.5 x = -7.29725976 + -7.5 Combine like terms: -7.29725976 + -7.5 = -14.79725976 x = -14.79725976 Simplifying x = -14.79725976Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.20274024, -14.79725976}Solution
x = {-0.20274024, -14.79725976}
