Simplifying 20a2b + -25ab + 45ab2 = 0 Reorder the terms: -25ab + 45ab2 + 20a2b = 0 Solving -25ab + 45ab2 + 20a2b = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '5ab'. 5ab(-5 + 9b + 4a) = 0 Ignore the factor 5.Subproblem 1
Set the factor 'ab' equal to zero and attempt to solve: Simplifying ab = 0 Solving ab = 0 Move all terms containing a to the left, all other terms to the right. Simplifying ab = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(-5 + 9b + 4a)' equal to zero and attempt to solve: Simplifying -5 + 9b + 4a = 0 Reorder the terms: -5 + 4a + 9b = 0 Solving -5 + 4a + 9b = 0 Move all terms containing a to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 4a + 5 + 9b = 0 + 5 Reorder the terms: -5 + 5 + 4a + 9b = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 4a + 9b = 0 + 5 4a + 9b = 0 + 5 Combine like terms: 0 + 5 = 5 4a + 9b = 5 Add '-9b' to each side of the equation. 4a + 9b + -9b = 5 + -9b Combine like terms: 9b + -9b = 0 4a + 0 = 5 + -9b 4a = 5 + -9b Divide each side by '4'. a = 1.25 + -2.25b Simplifying a = 1.25 + -2.25bSolution
a = {1.25 + -2.25b}
