Subproblem 1

Set the factor '(6 + -4x + x2)' equal to zero and attempt to solve: Simplifying 6 + -4x + x2 = 0 Solving 6 + -4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-6' to each side of the equation. 6 + -4x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + -4x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -4x + x2 = 0 + -6 -4x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 -4x + x2 = -6 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -6 + 4 Reorder the terms: 4 + -4x + x2 = -6 + 4 Combine like terms: -6 + 4 = -2 4 + -4x + x2 = -2 Factor a perfect square on the left side: (x + -2)(x + -2) = -2 Can't calculate square root of the right side.
