Simplifying 5x2 + -30x + 54 = 0 Reorder the terms: 54 + -30x + 5x2 = 0 Solving 54 + -30x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 10.8 + -6x + x2 = 0 Move the constant term to the right: Add '-10.8' to each side of the equation. 10.8 + -6x + -10.8 + x2 = 0 + -10.8 Reorder the terms: 10.8 + -10.8 + -6x + x2 = 0 + -10.8 Combine like terms: 10.8 + -10.8 = 0.0 0.0 + -6x + x2 = 0 + -10.8 -6x + x2 = 0 + -10.8 Combine like terms: 0 + -10.8 = -10.8 -6x + x2 = -10.8 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -10.8 + 9 Reorder the terms: 9 + -6x + x2 = -10.8 + 9 Combine like terms: -10.8 + 9 = -1.8 9 + -6x + x2 = -1.8 Factor a perfect square on the left side: (x + -3)(x + -3) = -1.8 Can't calculate square root of the right side. The solution to this equation could not be determined.
