Simplifying 4x2 + 15x + -60 = 0 Reorder the terms: -60 + 15x + 4x2 = 0 Solving -60 + 15x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -15 + 3.75x + x2 = 0 Move the constant term to the right: Add '15' to each side of the equation. -15 + 3.75x + 15 + x2 = 0 + 15 Reorder the terms: -15 + 15 + 3.75x + x2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + 3.75x + x2 = 0 + 15 3.75x + x2 = 0 + 15 Combine like terms: 0 + 15 = 15 3.75x + x2 = 15 The x term is 3.75x. Take half its coefficient (1.875). Square it (3.515625) and add it to both sides. Add '3.515625' to each side of the equation. 3.75x + 3.515625 + x2 = 15 + 3.515625 Reorder the terms: 3.515625 + 3.75x + x2 = 15 + 3.515625 Combine like terms: 15 + 3.515625 = 18.515625 3.515625 + 3.75x + x2 = 18.515625 Factor a perfect square on the left side: (x + 1.875)(x + 1.875) = 18.515625 Calculate the square root of the right side: 4.30297862 Break this problem into two subproblems by setting (x + 1.875) equal to 4.30297862 and -4.30297862.Subproblem 1
x + 1.875 = 4.30297862 Simplifying x + 1.875 = 4.30297862 Reorder the terms: 1.875 + x = 4.30297862 Solving 1.875 + x = 4.30297862 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.875' to each side of the equation. 1.875 + -1.875 + x = 4.30297862 + -1.875 Combine like terms: 1.875 + -1.875 = 0.000 0.000 + x = 4.30297862 + -1.875 x = 4.30297862 + -1.875 Combine like terms: 4.30297862 + -1.875 = 2.42797862 x = 2.42797862 Simplifying x = 2.42797862Subproblem 2
x + 1.875 = -4.30297862 Simplifying x + 1.875 = -4.30297862 Reorder the terms: 1.875 + x = -4.30297862 Solving 1.875 + x = -4.30297862 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.875' to each side of the equation. 1.875 + -1.875 + x = -4.30297862 + -1.875 Combine like terms: 1.875 + -1.875 = 0.000 0.000 + x = -4.30297862 + -1.875 x = -4.30297862 + -1.875 Combine like terms: -4.30297862 + -1.875 = -6.17797862 x = -6.17797862 Simplifying x = -6.17797862Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.42797862, -6.17797862}
