Simplifying (3a + -1b)(3a + -1b) = 0 Multiply (3a + -1b) * (3a + -1b) (3a * (3a + -1b) + -1b * (3a + -1b)) = 0 ((3a * 3a + -1b * 3a) + -1b * (3a + -1b)) = 0 Reorder the terms: ((-3ab + 9a2) + -1b * (3a + -1b)) = 0 ((-3ab + 9a2) + -1b * (3a + -1b)) = 0 (-3ab + 9a2 + (3a * -1b + -1b * -1b)) = 0 (-3ab + 9a2 + (-3ab + 1b2)) = 0 Reorder the terms: (-3ab + -3ab + 9a2 + 1b2) = 0 Combine like terms: -3ab + -3ab = -6ab (-6ab + 9a2 + 1b2) = 0 Solving -6ab + 9a2 + 1b2 = 0 Solving for variable 'a'. Factor a trinomial. (3a + -1b)(3a + -1b) = 0Subproblem 1
Set the factor '(3a + -1b)' equal to zero and attempt to solve: Simplifying 3a + -1b = 0 Solving 3a + -1b = 0 Move all terms containing a to the left, all other terms to the right. Add 'b' to each side of the equation. 3a + -1b + b = 0 + b Combine like terms: -1b + b = 0 3a + 0 = 0 + b 3a = 0 + b Remove the zero: 3a = b Divide each side by '3'. a = 0.3333333333b Simplifying a = 0.3333333333bSubproblem 2
