Subproblem 1

Set the factor '(45 + -6x + x2)' equal to zero and attempt to solve: Simplifying 45 + -6x + x2 = 0 Solving 45 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-45' to each side of the equation. 45 + -6x + -45 + x2 = 0 + -45 Reorder the terms: 45 + -45 + -6x + x2 = 0 + -45 Combine like terms: 45 + -45 = 0 0 + -6x + x2 = 0 + -45 -6x + x2 = 0 + -45 Combine like terms: 0 + -45 = -45 -6x + x2 = -45 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -45 + 9 Reorder the terms: 9 + -6x + x2 = -45 + 9 Combine like terms: -45 + 9 = -36 9 + -6x + x2 = -36 Factor a perfect square on the left side: (x + -3)(x + -3) = -36 Can't calculate square root of the right side.
