Simplifying -100x2 + 700x + -2000 = 0 Reorder the terms: -2000 + 700x + -100x2 = 0 Solving -2000 + 700x + -100x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '100'. 100(-20 + 7x + -1x2) = 0 Ignore the factor 100.Subproblem 1
Set the factor '(-20 + 7x + -1x2)' equal to zero and attempt to solve: Simplifying -20 + 7x + -1x2 = 0 Solving -20 + 7x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 20 + -7x + x2 = 0 Move the constant term to the right: Add '-20' to each side of the equation. 20 + -7x + -20 + x2 = 0 + -20 Reorder the terms: 20 + -20 + -7x + x2 = 0 + -20 Combine like terms: 20 + -20 = 0 0 + -7x + x2 = 0 + -20 -7x + x2 = 0 + -20 Combine like terms: 0 + -20 = -20 -7x + x2 = -20 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = -20 + 12.25 Reorder the terms: 12.25 + -7x + x2 = -20 + 12.25 Combine like terms: -20 + 12.25 = -7.75 12.25 + -7x + x2 = -7.75 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = -7.75 Can't calculate square root of the right side.
