How do you simplify #( 5a^2 + 20a) /( a^3-2a^2) * ( a^2-a-12) / (a^2-16)#?
simplyfing the first equation:
having a common factor "a"
simplifying The denominator:
having a common factor "
Moving to the second equation:
This equation cannot be solved by the common factor method, because -12 has no "a".
However, It can be solved by another method:
opening 2 different parenthesis
having the power common factor
By factoring each expression in the numerator(top) and the denominator(bottom) and then cancelling out the commons.
Here's how we do it:
This is an expression of the form :
