Simplifying 4x2 + -7x = -8 Reorder the terms: -7x + 4x2 = -8 Solving -7x + 4x2 = -8 Solving for variable 'x'. Reorder the terms: 8 + -7x + 4x2 = -8 + 8 Combine like terms: -8 + 8 = 0 8 + -7x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 2 + -1.75x + x2 = 0 Move the constant term to the right: Add '-2' to each side of the equation. 2 + -1.75x + -2 + x2 = 0 + -2 Reorder the terms: 2 + -2 + -1.75x + x2 = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1.75x + x2 = 0 + -2 -1.75x + x2 = 0 + -2 Combine like terms: 0 + -2 = -2 -1.75x + x2 = -2 The x term is -1.75x. Take half its coefficient (-0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. -1.75x + 0.765625 + x2 = -2 + 0.765625 Reorder the terms: 0.765625 + -1.75x + x2 = -2 + 0.765625 Combine like terms: -2 + 0.765625 = -1.234375 0.765625 + -1.75x + x2 = -1.234375 Factor a perfect square on the left side: (x + -0.875)(x + -0.875) = -1.234375 Can't calculate square root of the right side. The solution to this equation could not be determined.
