Simplifying 5x2 + -9x = -8 Reorder the terms: -9x + 5x2 = -8 Solving -9x + 5x2 = -8 Solving for variable 'x'. Reorder the terms: 8 + -9x + 5x2 = -8 + 8 Combine like terms: -8 + 8 = 0 8 + -9x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.6 + -1.8x + x2 = 0 Move the constant term to the right: Add '-1.6' to each side of the equation. 1.6 + -1.8x + -1.6 + x2 = 0 + -1.6 Reorder the terms: 1.6 + -1.6 + -1.8x + x2 = 0 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + -1.8x + x2 = 0 + -1.6 -1.8x + x2 = 0 + -1.6 Combine like terms: 0 + -1.6 = -1.6 -1.8x + x2 = -1.6 The x term is -1.8x. Take half its coefficient (-0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. -1.8x + 0.81 + x2 = -1.6 + 0.81 Reorder the terms: 0.81 + -1.8x + x2 = -1.6 + 0.81 Combine like terms: -1.6 + 0.81 = -0.79 0.81 + -1.8x + x2 = -0.79 Factor a perfect square on the left side: (x + -0.9)(x + -0.9) = -0.79 Can't calculate square root of the right side. The solution to this equation could not be determined.
