Simplifying -2x2 + 40x + -202 = 0 Reorder the terms: -202 + 40x + -2x2 = 0 Solving -202 + 40x + -2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-101 + 20x + -1x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-101 + 20x + -1x2)' equal to zero and attempt to solve: Simplifying -101 + 20x + -1x2 = 0 Solving -101 + 20x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 101 + -20x + x2 = 0 Move the constant term to the right: Add '-101' to each side of the equation. 101 + -20x + -101 + x2 = 0 + -101 Reorder the terms: 101 + -101 + -20x + x2 = 0 + -101 Combine like terms: 101 + -101 = 0 0 + -20x + x2 = 0 + -101 -20x + x2 = 0 + -101 Combine like terms: 0 + -101 = -101 -20x + x2 = -101 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -101 + 100 Reorder the terms: 100 + -20x + x2 = -101 + 100 Combine like terms: -101 + 100 = -1 100 + -20x + x2 = -1 Factor a perfect square on the left side: (x + -10)(x + -10) = -1 Can't calculate square root of the right side.
