Simplifying 4x2 + 4x = -17 Reorder the terms: 4x + 4x2 = -17 Solving 4x + 4x2 = -17 Solving for variable 'x'. Reorder the terms: 17 + 4x + 4x2 = -17 + 17 Combine like terms: -17 + 17 = 0 17 + 4x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 4.25 + x + x2 = 0 Move the constant term to the right: Add '-4.25' to each side of the equation. 4.25 + x + -4.25 + x2 = 0 + -4.25 Reorder the terms: 4.25 + -4.25 + x + x2 = 0 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + x + x2 = 0 + -4.25 x + x2 = 0 + -4.25 Combine like terms: 0 + -4.25 = -4.25 x + x2 = -4.25 The x term is x. 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. + 0.25 + x2 = -4.25 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = -4.25 + 0.25 Combine like terms: -4.25 + 0.25 = -4 1.25 + x2 = -4 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
