This week I learned how to multiply rational expressions.
Here is a common question:
This question asked me to simplify the expression. The first thing i did in this question was reduce the coefficients, and then I combined the two expressions together since it was multiplying. After I factored out what I could from the expression to figure out which factors can cancel out. Then i just reduced a to figure out my answer. The last step was to find out the non-permissible for a, and this means the values that will not make the denominator equal to zero. This is because in a division question you aren’t allowed to have the denominator equal to zero.
