Simplifying 0 = 9 + 4x2 + -16x Reorder the terms: 0 = 9 + -16x + 4x2 Solving 0 = 9 + -16x + 4x2 Solving for variable 'x'. Combine like terms: 0 + -9 = -9 -9 + 16x + -4x2 = 9 + -16x + 4x2 + -9 + 16x + -4x2 Reorder the terms: -9 + 16x + -4x2 = 9 + -9 + -16x + 16x + 4x2 + -4x2 Combine like terms: 9 + -9 = 0 -9 + 16x + -4x2 = 0 + -16x + 16x + 4x2 + -4x2 -9 + 16x + -4x2 = -16x + 16x + 4x2 + -4x2 Combine like terms: -16x + 16x = 0 -9 + 16x + -4x2 = 0 + 4x2 + -4x2 -9 + 16x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 -9 + 16x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 2.25 + -4x + x2 = 0 Move the constant term to the right: Add '-2.25' to each side of the equation. 2.25 + -4x + -2.25 + x2 = 0 + -2.25 Reorder the terms: 2.25 + -2.25 + -4x + x2 = 0 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + -4x + x2 = 0 + -2.25 -4x + x2 = 0 + -2.25 Combine like terms: 0 + -2.25 = -2.25 -4x + x2 = -2.25 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 = -2.25 + 4 Reorder the terms: 4 + -4x + x2 = -2.25 + 4 Combine like terms: -2.25 + 4 = 1.75 4 + -4x + x2 = 1.75 Factor a perfect square on the left side: (x + -2)(x + -2) = 1.75 Calculate the square root of the right side: 1.322875656 Break this problem into two subproblems by setting (x + -2) equal to 1.322875656 and -1.322875656.Subproblem 1
x + -2 = 1.322875656 Simplifying x + -2 = 1.322875656 Reorder the terms: -2 + x = 1.322875656 Solving -2 + x = 1.322875656 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 = 1.322875656 + 2 Combine like terms: -2 + 2 = 0 0 + x = 1.322875656 + 2 x = 1.322875656 + 2 Combine like terms: 1.322875656 + 2 = 3.322875656 x = 3.322875656 Simplifying x = 3.322875656Subproblem 2
x + -2 = -1.322875656 Simplifying x + -2 = -1.322875656 Reorder the terms: -2 + x = -1.322875656 Solving -2 + x = -1.322875656 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 = -1.322875656 + 2 Combine like terms: -2 + 2 = 0 0 + x = -1.322875656 + 2 x = -1.322875656 + 2 Combine like terms: -1.322875656 + 2 = 0.677124344 x = 0.677124344 Simplifying x = 0.677124344Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.322875656, 0.677124344}
