Simplifying x2 + 3x + 99 = 2 Reorder the terms: 99 + 3x + x2 = 2 Solving 99 + 3x + x2 = 2 Solving for variable 'x'. Reorder the terms: 99 + -2 + 3x + x2 = 2 + -2 Combine like terms: 99 + -2 = 97 97 + 3x + x2 = 2 + -2 Combine like terms: 2 + -2 = 0 97 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-97' to each side of the equation. 97 + 3x + -97 + x2 = 0 + -97 Reorder the terms: 97 + -97 + 3x + x2 = 0 + -97 Combine like terms: 97 + -97 = 0 0 + 3x + x2 = 0 + -97 3x + x2 = 0 + -97 Combine like terms: 0 + -97 = -97 3x + x2 = -97 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = -97 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -97 + 2.25 Combine like terms: -97 + 2.25 = -94.75 2.25 + 3x + x2 = -94.75 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = -94.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
