Simplifying 8(x2 + -1x) = x2 + -7 Reorder the terms: 8(-1x + x2) = x2 + -7 (-1x * 8 + x2 * 8) = x2 + -7 (-8x + 8x2) = x2 + -7 Reorder the terms: -8x + 8x2 = -7 + x2 Solving -8x + 8x2 = -7 + x2 Solving for variable 'x'. Reorder the terms: 7 + -8x + 8x2 + -1x2 = -7 + x2 + 7 + -1x2 Combine like terms: 8x2 + -1x2 = 7x2 7 + -8x + 7x2 = -7 + x2 + 7 + -1x2 Reorder the terms: 7 + -8x + 7x2 = -7 + 7 + x2 + -1x2 Combine like terms: -7 + 7 = 0 7 + -8x + 7x2 = 0 + x2 + -1x2 7 + -8x + 7x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 7 + -8x + 7x2 = 0 Begin completing the square. Divide all terms by 7 the coefficient of the squared term: Divide each side by '7'. 1 + -1.142857143x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + -1.142857143x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + -1.142857143x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1.142857143x + x2 = 0 + -1 -1.142857143x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 -1.142857143x + x2 = -1 The x term is -1.142857143x. Take half its coefficient (-0.5714285715). Square it (0.3265306123) and add it to both sides. Add '0.3265306123' to each side of the equation. -1.142857143x + 0.3265306123 + x2 = -1 + 0.3265306123 Reorder the terms: 0.3265306123 + -1.142857143x + x2 = -1 + 0.3265306123 Combine like terms: -1 + 0.3265306123 = -0.6734693877 0.3265306123 + -1.142857143x + x2 = -0.6734693877 Factor a perfect square on the left side: (x + -0.5714285715)(x + -0.5714285715) = -0.6734693877 Can't calculate square root of the right side. The solution to this equation could not be determined.
