Simplifying 5x2 = 12x + -9 Reorder the terms: 5x2 = -9 + 12x Solving 5x2 = -9 + 12x Solving for variable 'x'. Reorder the terms: 9 + -12x + 5x2 = -9 + 12x + 9 + -12x Reorder the terms: 9 + -12x + 5x2 = -9 + 9 + 12x + -12x Combine like terms: -9 + 9 = 0 9 + -12x + 5x2 = 0 + 12x + -12x 9 + -12x + 5x2 = 12x + -12x Combine like terms: 12x + -12x = 0 9 + -12x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.8 + -2.4x + x2 = 0 Move the constant term to the right: Add '-1.8' to each side of the equation. 1.8 + -2.4x + -1.8 + x2 = 0 + -1.8 Reorder the terms: 1.8 + -1.8 + -2.4x + x2 = 0 + -1.8 Combine like terms: 1.8 + -1.8 = 0.0 0.0 + -2.4x + x2 = 0 + -1.8 -2.4x + x2 = 0 + -1.8 Combine like terms: 0 + -1.8 = -1.8 -2.4x + x2 = -1.8 The x term is -2.4x. Take half its coefficient (-1.2). Square it (1.44) and add it to both sides. Add '1.44' to each side of the equation. -2.4x + 1.44 + x2 = -1.8 + 1.44 Reorder the terms: 1.44 + -2.4x + x2 = -1.8 + 1.44 Combine like terms: -1.8 + 1.44 = -0.36 1.44 + -2.4x + x2 = -0.36 Factor a perfect square on the left side: (x + -1.2)(x + -1.2) = -0.36 Can't calculate square root of the right side. The solution to this equation could not be determined.
