Simplifying 10x + -6 = 5x2 Reorder the terms: -6 + 10x = 5x2 Solving -6 + 10x = 5x2 Solving for variable 'x'. Combine like terms: 5x2 + -5x2 = 0 -6 + 10x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 1.2 + -2x + x2 = 0 Move the constant term to the right: Add '-1.2' to each side of the equation. 1.2 + -2x + -1.2 + x2 = 0 + -1.2 Reorder the terms: 1.2 + -1.2 + -2x + x2 = 0 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + -2x + x2 = 0 + -1.2 -2x + x2 = 0 + -1.2 Combine like terms: 0 + -1.2 = -1.2 -2x + x2 = -1.2 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -1.2 + 1 Reorder the terms: 1 + -2x + x2 = -1.2 + 1 Combine like terms: -1.2 + 1 = -0.2 1 + -2x + x2 = -0.2 Factor a perfect square on the left side: (x + -1)(x + -1) = -0.2 Can't calculate square root of the right side. The solution to this equation could not be determined.
