Simplifying 2x2 + -18x + -3 = 0 Reorder the terms: -3 + -18x + 2x2 = 0 Solving -3 + -18x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + -9x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -9x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -9x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -9x + x2 = 0 + 1.5 -9x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -9x + x2 = 1.5 The x term is -9x. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9x + 20.25 + x2 = 1.5 + 20.25 Reorder the terms: 20.25 + -9x + x2 = 1.5 + 20.25 Combine like terms: 1.5 + 20.25 = 21.75 20.25 + -9x + x2 = 21.75 Factor a perfect square on the left side: (x + -4.5)(x + -4.5) = 21.75 Calculate the square root of the right side: 4.663689527 Break this problem into two subproblems by setting (x + -4.5) equal to 4.663689527 and -4.663689527.Subproblem 1
x + -4.5 = 4.663689527 Simplifying x + -4.5 = 4.663689527 Reorder the terms: -4.5 + x = 4.663689527 Solving -4.5 + x = 4.663689527 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = 4.663689527 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = 4.663689527 + 4.5 x = 4.663689527 + 4.5 Combine like terms: 4.663689527 + 4.5 = 9.163689527 x = 9.163689527 Simplifying x = 9.163689527Subproblem 2
x + -4.5 = -4.663689527 Simplifying x + -4.5 = -4.663689527 Reorder the terms: -4.5 + x = -4.663689527 Solving -4.5 + x = -4.663689527 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + x = -4.663689527 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + x = -4.663689527 + 4.5 x = -4.663689527 + 4.5 Combine like terms: -4.663689527 + 4.5 = -0.163689527 x = -0.163689527 Simplifying x = -0.163689527Solution
