Simplifying 8x2 + 10x + 21 = 0 Reorder the terms: 21 + 10x + 8x2 = 0 Solving 21 + 10x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 2.625 + 1.25x + x2 = 0 Move the constant term to the right: Add '-2.625' to each side of the equation. 2.625 + 1.25x + -2.625 + x2 = 0 + -2.625 Reorder the terms: 2.625 + -2.625 + 1.25x + x2 = 0 + -2.625 Combine like terms: 2.625 + -2.625 = 0.000 0.000 + 1.25x + x2 = 0 + -2.625 1.25x + x2 = 0 + -2.625 Combine like terms: 0 + -2.625 = -2.625 1.25x + x2 = -2.625 The x term is 1.25x. Take half its coefficient (0.625). Square it (0.390625) and add it to both sides. Add '0.390625' to each side of the equation. 1.25x + 0.390625 + x2 = -2.625 + 0.390625 Reorder the terms: 0.390625 + 1.25x + x2 = -2.625 + 0.390625 Combine like terms: -2.625 + 0.390625 = -2.234375 0.390625 + 1.25x + x2 = -2.234375 Factor a perfect square on the left side: (x + 0.625)(x + 0.625) = -2.234375 Can't calculate square root of the right side. The solution to this equation could not be determined.
