Simplifying 10x2 + 8x + 7 = 0 Reorder the terms: 7 + 8x + 10x2 = 0 Solving 7 + 8x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.7 + 0.8x + x2 = 0 Move the constant term to the right: Add '-0.7' to each side of the equation. 0.7 + 0.8x + -0.7 + x2 = 0 + -0.7 Reorder the terms: 0.7 + -0.7 + 0.8x + x2 = 0 + -0.7 Combine like terms: 0.7 + -0.7 = 0.0 0.0 + 0.8x + x2 = 0 + -0.7 0.8x + x2 = 0 + -0.7 Combine like terms: 0 + -0.7 = -0.7 0.8x + x2 = -0.7 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = -0.7 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = -0.7 + 0.16 Combine like terms: -0.7 + 0.16 = -0.54 0.16 + 0.8x + x2 = -0.54 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = -0.54 Can't calculate square root of the right side. The solution to this equation could not be determined.
