Simplifying 800 = -5x2 + 10x + 7 Reorder the terms: 800 = 7 + 10x + -5x2 Solving 800 = 7 + 10x + -5x2 Solving for variable 'x'. Combine like terms: 800 + -7 = 793 793 + -10x + 5x2 = 7 + 10x + -5x2 + -7 + -10x + 5x2 Reorder the terms: 793 + -10x + 5x2 = 7 + -7 + 10x + -10x + -5x2 + 5x2 Combine like terms: 7 + -7 = 0 793 + -10x + 5x2 = 0 + 10x + -10x + -5x2 + 5x2 793 + -10x + 5x2 = 10x + -10x + -5x2 + 5x2 Combine like terms: 10x + -10x = 0 793 + -10x + 5x2 = 0 + -5x2 + 5x2 793 + -10x + 5x2 = -5x2 + 5x2 Combine like terms: -5x2 + 5x2 = 0 793 + -10x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 158.6 + -2x + x2 = 0 Move the constant term to the right: Add '-158.6' to each side of the equation. 158.6 + -2x + -158.6 + x2 = 0 + -158.6 Reorder the terms: 158.6 + -158.6 + -2x + x2 = 0 + -158.6 Combine like terms: 158.6 + -158.6 = 0.0 0.0 + -2x + x2 = 0 + -158.6 -2x + x2 = 0 + -158.6 Combine like terms: 0 + -158.6 = -158.6 -2x + x2 = -158.6 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 = -158.6 + 1 Reorder the terms: 1 + -2x + x2 = -158.6 + 1 Combine like terms: -158.6 + 1 = -157.6 1 + -2x + x2 = -157.6 Factor a perfect square on the left side: (x + -1)(x + -1) = -157.6 Can't calculate square root of the right side. The solution to this equation could not be determined.
