Today in class we learnt how to multiply monomials and polynomials. Basically all you have to do is multiply the monomial outside of the brackets by the polynomial inside the brackets.
We also learnt how to simplify these expressions. To simplify an expression you, first, expand the expression like we have already done and then, secondly, collect like terms.
Ex: Expand and Simplify
4x(2x²+ 5x -3) –(2x²-7)
The final thing that we learnt to do today was multiplying binomials. When multiplying binomials you use the F.O.I.L. method. The F.O.I.L. method stands for multiplying the First two terms, then multiplying the Outside two terms, then multiplying the Inside two terms, and, finally, multiplying the Last two terms.
Ex: Find the product of the binomials
=x²+8x+6x +48 <----(F.O.I.L. method)
=x²+14x+48 <----( you have to collect like terms here too.)
