Simplifying -1.80 = 4.9x + -4.9(x2) Solving -1.80 = 4.9x + -4.9x2 Solving for variable 'x'. Reorder the terms: -1.80 + -4.9x + 4.9x2 = 4.9x + -4.9x + -4.9x2 + 4.9x2 Combine like terms: 4.9x + -4.9x = 0.0 -1.80 + -4.9x + 4.9x2 = 0.0 + -4.9x2 + 4.9x2 -1.80 + -4.9x + 4.9x2 = -4.9x2 + 4.9x2 Combine like terms: -4.9x2 + 4.9x2 = 0.0 -1.80 + -4.9x + 4.9x2 = 0.0 Begin completing the square. Divide all terms by 4.9 the coefficient of the squared term: Divide each side by '4.9'. -0.3673469388 + -1x + x2 = 0 Move the constant term to the right: Add '0.3673469388' to each side of the equation. -0.3673469388 + -1x + 0.3673469388 + x2 = 0 + 0.3673469388 Reorder the terms: -0.3673469388 + 0.3673469388 + -1x + x2 = 0 + 0.3673469388 Combine like terms: -0.3673469388 + 0.3673469388 = 0.0000000000 0.0000000000 + -1x + x2 = 0 + 0.3673469388 -1x + x2 = 0 + 0.3673469388 Combine like terms: 0 + 0.3673469388 = 0.3673469388 -1x + x2 = 0.3673469388 The x term is -1x. 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. -1x + 0.25 + x2 = 0.3673469388 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 0.3673469388 + 0.25 Combine like terms: 0.3673469388 + 0.25 = 0.6173469388 0.25 + -1x + x2 = 0.6173469388 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 0.6173469388 Calculate the square root of the right side: 0.785714286 Break this problem into two subproblems by setting (x + -0.5) equal to 0.785714286 and -0.785714286.Subproblem 1
x + -0.5 = 0.785714286 Simplifying x + -0.5 = 0.785714286 Reorder the terms: -0.5 + x = 0.785714286 Solving -0.5 + x = 0.785714286 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 = 0.785714286 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 0.785714286 + 0.5 x = 0.785714286 + 0.5 Combine like terms: 0.785714286 + 0.5 = 1.285714286 x = 1.285714286 Simplifying x = 1.285714286Subproblem 2
x + -0.5 = -0.785714286 Simplifying x + -0.5 = -0.785714286 Reorder the terms: -0.5 + x = -0.785714286 Solving -0.5 + x = -0.785714286 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 = -0.785714286 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -0.785714286 + 0.5 x = -0.785714286 + 0.5 Combine like terms: -0.785714286 + 0.5 = -0.285714286 x = -0.285714286 Simplifying x = -0.285714286Solution
