x-4 multiplied by x-3 equals what? 2x-1 multiplied by x-3 equals what?
I tried doing each problem each time and whenever it is in fraction form since that is how it is suppose to be written, it doesn't look right. What could I be doing wrong?

When multiplying binomials, we use FOIL or First Outside Inside Last to express the product as a sum of terms.
First-multiply first two terms of the two binomials.
Outside-multiply the first terms of the first binomial with the last term of the second binomial.
Inside-multiply the last term of the first binomial and the first term of the second binomial
last-multiply the last term of both binomials.
then combine like terms
Hope this helped. Peace.
