Simplifying 4x2 + -7x = -5 Reorder the terms: -7x + 4x2 = -5 Solving -7x + 4x2 = -5 Solving for variable 'x'. Reorder the terms: 5 + -7x + 4x2 = -5 + 5 Combine like terms: -5 + 5 = 0 5 + -7x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.25 + -1.75x + x2 = 0 Move the constant term to the right: Add '-1.25' to each side of the equation. 1.25 + -1.75x + -1.25 + x2 = 0 + -1.25 Reorder the terms: 1.25 + -1.25 + -1.75x + x2 = 0 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + -1.75x + x2 = 0 + -1.25 -1.75x + x2 = 0 + -1.25 Combine like terms: 0 + -1.25 = -1.25 -1.75x + x2 = -1.25 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 = -1.25 + 0.765625 Reorder the terms: 0.765625 + -1.75x + x2 = -1.25 + 0.765625 Combine like terms: -1.25 + 0.765625 = -0.484375 0.765625 + -1.75x + x2 = -0.484375 Factor a perfect square on the left side: (x + -0.875)(x + -0.875) = -0.484375 Can't calculate square root of the right side. The solution to this equation could not be determined.
