Simplifying 3a2 + 17ab + 20b2 = 0 Reorder the terms: 17ab + 3a2 + 20b2 = 0 Solving 17ab + 3a2 + 20b2 = 0 Solving for variable 'a'. Factor a trinomial. (3a + 5b)(a + 4b) = 0Subproblem 1
Set the factor '(3a + 5b)' equal to zero and attempt to solve: Simplifying 3a + 5b = 0 Solving 3a + 5b = 0 Move all terms containing a to the left, all other terms to the right. Add '-5b' to each side of the equation. 3a + 5b + -5b = 0 + -5b Combine like terms: 5b + -5b = 0 3a + 0 = 0 + -5b 3a = 0 + -5b Remove the zero: 3a = -5b Divide each side by '3'. a = -1.666666667b Simplifying a = -1.666666667bSubproblem 2
Set the factor '(a + 4b)' equal to zero and attempt to solve: Simplifying a + 4b = 0 Solving a + 4b = 0 Move all terms containing a to the left, all other terms to the right. Add '-4b' to each side of the equation. a + 4b + -4b = 0 + -4b Combine like terms: 4b + -4b = 0 a + 0 = 0 + -4b a = 0 + -4b Remove the zero: a = -4b Simplifying a = -4bSolution
a = {-1.666666667b, -4b}
