Simplifying 7 + 16x + -4x2 = 0 Solving 7 + 16x + -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'. -1.75 + -4x + x2 = 0 Move the constant term to the right: Add '1.75' to each side of the equation. -1.75 + -4x + 1.75 + x2 = 0 + 1.75 Reorder the terms: -1.75 + 1.75 + -4x + x2 = 0 + 1.75 Combine like terms: -1.75 + 1.75 = 0.00 0.00 + -4x + x2 = 0 + 1.75 -4x + x2 = 0 + 1.75 Combine like terms: 0 + 1.75 = 1.75 -4x + x2 = 1.75 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = 1.75 + 4 Reorder the terms: 4 + -4x + x2 = 1.75 + 4 Combine like terms: 1.75 + 4 = 5.75 4 + -4x + x2 = 5.75 Factor a perfect square on the left side: (x + -2)(x + -2) = 5.75 Calculate the square root of the right side: 2.397915762 Break this problem into two subproblems by setting (x + -2) equal to 2.397915762 and -2.397915762.Subproblem 1
x + -2 = 2.397915762 Simplifying x + -2 = 2.397915762 Reorder the terms: -2 + x = 2.397915762 Solving -2 + x = 2.397915762 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 2.397915762 + 2 Combine like terms: -2 + 2 = 0 0 + x = 2.397915762 + 2 x = 2.397915762 + 2 Combine like terms: 2.397915762 + 2 = 4.397915762 x = 4.397915762 Simplifying x = 4.397915762Subproblem 2
x + -2 = -2.397915762 Simplifying x + -2 = -2.397915762 Reorder the terms: -2 + x = -2.397915762 Solving -2 + x = -2.397915762 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -2.397915762 + 2 Combine like terms: -2 + 2 = 0 0 + x = -2.397915762 + 2 x = -2.397915762 + 2 Combine like terms: -2.397915762 + 2 = -0.397915762 x = -0.397915762 Simplifying x = -0.397915762Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.397915762, -0.397915762}
