Simplifying -0.2x2 + 0.9x + 2.2 = 0 Reorder the terms: 2.2 + 0.9x + -0.2x2 = 0 Solving 2.2 + 0.9x + -0.2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.2 the coefficient of the squared term: Divide each side by '-0.2'. -11 + -4.5x + x2 = 0 Move the constant term to the right: Add '11' to each side of the equation. -11 + -4.5x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + -4.5x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -4.5x + x2 = 0 + 11 -4.5x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 -4.5x + x2 = 11 The x term is -4.5x. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5x + 5.0625 + x2 = 11 + 5.0625 Reorder the terms: 5.0625 + -4.5x + x2 = 11 + 5.0625 Combine like terms: 11 + 5.0625 = 16.0625 5.0625 + -4.5x + x2 = 16.0625 Factor a perfect square on the left side: (x + -2.25)(x + -2.25) = 16.0625 Calculate the square root of the right side: 4.007804885 Break this problem into two subproblems by setting (x + -2.25) equal to 4.007804885 and -4.007804885.Subproblem 1
x + -2.25 = 4.007804885 Simplifying x + -2.25 = 4.007804885 Reorder the terms: -2.25 + x = 4.007804885 Solving -2.25 + x = 4.007804885 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + x = 4.007804885 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + x = 4.007804885 + 2.25 x = 4.007804885 + 2.25 Combine like terms: 4.007804885 + 2.25 = 6.257804885 x = 6.257804885 Simplifying x = 6.257804885Subproblem 2
x + -2.25 = -4.007804885 Simplifying x + -2.25 = -4.007804885 Reorder the terms: -2.25 + x = -4.007804885 Solving -2.25 + x = -4.007804885 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + x = -4.007804885 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + x = -4.007804885 + 2.25 x = -4.007804885 + 2.25 Combine like terms: -4.007804885 + 2.25 = -1.757804885 x = -1.757804885 Simplifying x = -1.757804885Solution
