Simplifying 8a2b + -28a2 = 0 Reorder the terms: -28a2 + 8a2b = 0 Solving -28a2 + 8a2b = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), '4a2'. 4a2(-7 + 2b) = 0 Ignore the factor 4.Subproblem 1
Set the factor 'a2' equal to zero and attempt to solve: Simplifying a2 = 0 Solving a2 = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a2 = 0 Take the square root of each side: a = {0}Subproblem 2
Set the factor '(-7 + 2b)' equal to zero and attempt to solve: Simplifying -7 + 2b = 0 Solving -7 + 2b = 0 Move all terms containing a to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + 2b = 0 + 7 Combine like terms: -7 + 7 = 0 0 + 2b = 0 + 7 2b = 0 + 7 Combine like terms: 0 + 7 = 7 2b = 7 Add '-2b' to each side of the equation. 2b + -2b = 7 + -2b Combine like terms: 2b + -2b = 0 0 = 7 + -2b Simplifying 0 = 7 + -2b The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
