Simplifying 3x2 + 3x + 6 = 20 Reorder the terms: 6 + 3x + 3x2 = 20 Solving 6 + 3x + 3x2 = 20 Solving for variable 'x'. Reorder the terms: 6 + -20 + 3x + 3x2 = 20 + -20 Combine like terms: 6 + -20 = -14 -14 + 3x + 3x2 = 20 + -20 Combine like terms: 20 + -20 = 0 -14 + 3x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -4.666666667 + x + x2 = 0 Move the constant term to the right: Add '4.666666667' to each side of the equation. -4.666666667 + x + 4.666666667 + x2 = 0 + 4.666666667 Reorder the terms: -4.666666667 + 4.666666667 + x + x2 = 0 + 4.666666667 Combine like terms: -4.666666667 + 4.666666667 = 0.000000000 0.000000000 + x + x2 = 0 + 4.666666667 x + x2 = 0 + 4.666666667 Combine like terms: 0 + 4.666666667 = 4.666666667 x + x2 = 4.666666667 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + x2 = 4.666666667 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 4.666666667 + 0.25 Combine like terms: 4.666666667 + 0.25 = 4.916666667 1.25 + x2 = 4.916666667 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 4.916666667 Calculate the square root of the right side: 2.217355783 Break this problem into two subproblems by setting (x + 0.5) equal to 2.217355783 and -2.217355783.Subproblem 1
x + 0.5 = 2.217355783 Simplifying x + 0.5 = 2.217355783 Reorder the terms: 0.5 + x = 2.217355783 Solving 0.5 + x = 2.217355783 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 2.217355783 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 2.217355783 + -0.5 x = 2.217355783 + -0.5 Combine like terms: 2.217355783 + -0.5 = 1.717355783 x = 1.717355783 Simplifying x = 1.717355783Subproblem 2
x + 0.5 = -2.217355783 Simplifying x + 0.5 = -2.217355783 Reorder the terms: 0.5 + x = -2.217355783 Solving 0.5 + x = -2.217355783 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -2.217355783 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -2.217355783 + -0.5 x = -2.217355783 + -0.5 Combine like terms: -2.217355783 + -0.5 = -2.717355783 x = -2.717355783 Simplifying x = -2.717355783Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.717355783, -2.717355783}
