Simplifying 8x2 = 22x + -21 Reorder the terms: 8x2 = -21 + 22x Solving 8x2 = -21 + 22x Solving for variable 'x'. Reorder the terms: 21 + -22x + 8x2 = -21 + 22x + 21 + -22x Reorder the terms: 21 + -22x + 8x2 = -21 + 21 + 22x + -22x Combine like terms: -21 + 21 = 0 21 + -22x + 8x2 = 0 + 22x + -22x 21 + -22x + 8x2 = 22x + -22x Combine like terms: 22x + -22x = 0 21 + -22x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 2.625 + -2.75x + x2 = 0 Move the constant term to the right: Add '-2.625' to each side of the equation. 2.625 + -2.75x + -2.625 + x2 = 0 + -2.625 Reorder the terms: 2.625 + -2.625 + -2.75x + x2 = 0 + -2.625 Combine like terms: 2.625 + -2.625 = 0.000 0.000 + -2.75x + x2 = 0 + -2.625 -2.75x + x2 = 0 + -2.625 Combine like terms: 0 + -2.625 = -2.625 -2.75x + x2 = -2.625 The x term is -2.75x. Take half its coefficient (-1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. -2.75x + 1.890625 + x2 = -2.625 + 1.890625 Reorder the terms: 1.890625 + -2.75x + x2 = -2.625 + 1.890625 Combine like terms: -2.625 + 1.890625 = -0.734375 1.890625 + -2.75x + x2 = -0.734375 Factor a perfect square on the left side: (x + -1.375)(x + -1.375) = -0.734375 Can't calculate square root of the right side. The solution to this equation could not be determined.
