Simplifying 4x2 + -11x + 15 = 0 Reorder the terms: 15 + -11x + 4x2 = 0 Solving 15 + -11x + 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'. 3.75 + -2.75x + x2 = 0 Move the constant term to the right: Add '-3.75' to each side of the equation. 3.75 + -2.75x + -3.75 + x2 = 0 + -3.75 Reorder the terms: 3.75 + -3.75 + -2.75x + x2 = 0 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + -2.75x + x2 = 0 + -3.75 -2.75x + x2 = 0 + -3.75 Combine like terms: 0 + -3.75 = -3.75 -2.75x + x2 = -3.75 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 = -3.75 + 1.890625 Reorder the terms: 1.890625 + -2.75x + x2 = -3.75 + 1.890625 Combine like terms: -3.75 + 1.890625 = -1.859375 1.890625 + -2.75x + x2 = -1.859375 Factor a perfect square on the left side: (x + -1.375)(x + -1.375) = -1.859375 Can't calculate square root of the right side. The solution to this equation could not be determined.
