Simplifying 7 = -4x + -10x2 Solving 7 = -4x + -10x2 Solving for variable 'x'. Reorder the terms: 7 + 4x + 10x2 = -4x + 4x + -10x2 + 10x2 Combine like terms: -4x + 4x = 0 7 + 4x + 10x2 = 0 + -10x2 + 10x2 7 + 4x + 10x2 = -10x2 + 10x2 Combine like terms: -10x2 + 10x2 = 0 7 + 4x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.7 + 0.4x + x2 = 0 Move the constant term to the right: Add '-0.7' to each side of the equation. 0.7 + 0.4x + -0.7 + x2 = 0 + -0.7 Reorder the terms: 0.7 + -0.7 + 0.4x + x2 = 0 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + 0.4x + x2 = 0 + -0.7 0.4x + x2 = 0 + -0.7 Combine like terms: 0 + -0.7 = -0.7 0.4x + x2 = -0.7 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = -0.7 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = -0.7 + 0.04 Combine like terms: -0.7 + 0.04 = -0.66 0.04 + 0.4x + x2 = -0.66 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = -0.66 Can't calculate square root of the right side. The solution to this equation could not be determined.
