Simplifying 2x2 + 36 = 17x + -30 Reorder the terms: 36 + 2x2 = 17x + -30 Reorder the terms: 36 + 2x2 = -30 + 17x Solving 36 + 2x2 = -30 + 17x Solving for variable 'x'. Reorder the terms: 36 + 30 + -17x + 2x2 = -30 + 17x + 30 + -17x Combine like terms: 36 + 30 = 66 66 + -17x + 2x2 = -30 + 17x + 30 + -17x Reorder the terms: 66 + -17x + 2x2 = -30 + 30 + 17x + -17x Combine like terms: -30 + 30 = 0 66 + -17x + 2x2 = 0 + 17x + -17x 66 + -17x + 2x2 = 17x + -17x Combine like terms: 17x + -17x = 0 66 + -17x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 33 + -8.5x + x2 = 0 Move the constant term to the right: Add '-33' to each side of the equation. 33 + -8.5x + -33 + x2 = 0 + -33 Reorder the terms: 33 + -33 + -8.5x + x2 = 0 + -33 Combine like terms: 33 + -33 = 0 0 + -8.5x + x2 = 0 + -33 -8.5x + x2 = 0 + -33 Combine like terms: 0 + -33 = -33 -8.5x + x2 = -33 The x term is -8.5x. Take half its coefficient (-4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. -8.5x + 18.0625 + x2 = -33 + 18.0625 Reorder the terms: 18.0625 + -8.5x + x2 = -33 + 18.0625 Combine like terms: -33 + 18.0625 = -14.9375 18.0625 + -8.5x + x2 = -14.9375 Factor a perfect square on the left side: (x + -4.25)(x + -4.25) = -14.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
