Simplifying x2 = 3(x + -3) Reorder the terms: x2 = 3(-3 + x) x2 = (-3 * 3 + x * 3) x2 = (-9 + 3x) Solving x2 = -9 + 3x Solving for variable 'x'. Reorder the terms: 9 + -3x + x2 = -9 + 3x + 9 + -3x Reorder the terms: 9 + -3x + x2 = -9 + 9 + 3x + -3x Combine like terms: -9 + 9 = 0 9 + -3x + x2 = 0 + 3x + -3x 9 + -3x + x2 = 3x + -3x Combine like terms: 3x + -3x = 0 9 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-9' to each side of the equation. 9 + -3x + -9 + x2 = 0 + -9 Reorder the terms: 9 + -9 + -3x + x2 = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -3x + x2 = 0 + -9 -3x + x2 = 0 + -9 Combine like terms: 0 + -9 = -9 -3x + x2 = -9 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 = -9 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -9 + 2.25 Combine like terms: -9 + 2.25 = -6.75 2.25 + -3x + x2 = -6.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -6.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
