Simplifying -4(x2) + 15x + -8 = 0 Reorder the terms: -8 + 15x + -4x2 = 0 Solving -8 + 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'. 2 + -3.75x + x2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -3.75x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + -3.75x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -3.75x + x2 = 0 + -2 -3.75x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -3.75x + x2 = -2 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 = -2 + 3.515625 Reorder the terms: 3.515625 + -3.75x + x2 = -2 + 3.515625 Combine like terms: -2 + 3.515625 = 1.515625 3.515625 + -3.75x + x2 = 1.515625 Factor a perfect square on the left side: (x + -1.875)(x + -1.875) = 1.515625 Calculate the square root of the right side: 1.231107225 Break this problem into two subproblems by setting (x + -1.875) equal to 1.231107225 and -1.231107225.Subproblem 1
x + -1.875 = 1.231107225 Simplifying x + -1.875 = 1.231107225 Reorder the terms: -1.875 + x = 1.231107225 Solving -1.875 + x = 1.231107225 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 = 1.231107225 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + x = 1.231107225 + 1.875 x = 1.231107225 + 1.875 Combine like terms: 1.231107225 + 1.875 = 3.106107225 x = 3.106107225 Simplifying x = 3.106107225Subproblem 2
x + -1.875 = -1.231107225 Simplifying x + -1.875 = -1.231107225 Reorder the terms: -1.875 + x = -1.231107225 Solving -1.875 + x = -1.231107225 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 = -1.231107225 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + x = -1.231107225 + 1.875 x = -1.231107225 + 1.875 Combine like terms: -1.231107225 + 1.875 = 0.643892775 x = 0.643892775 Simplifying x = 0.643892775Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.106107225, 0.643892775}
