Simplifying -4x2 + 8x + -7 = 0 Reorder the terms: -7 + 8x + -4x2 = 0 Solving -7 + 8x + -4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. 1.75 + -2x + x2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + -2x + -1.75 + x2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + -2x + x2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + -2x + x2 = 0 + -1.75 -2x + x2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 -2x + x2 = -1.75 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = -1.75 + 1 Reorder the terms: 1 + -2x + x2 = -1.75 + 1 Combine like terms: -1.75 + 1 = -0.75 1 + -2x + x2 = -0.75 Factor a perfect square on the left side: (x + -1)(x + -1) = -0.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
