How Do We Multiply Binomials ?

To multiply binomials you need to use the FOIL Method.


FOIL abbriviate:


First
Outer
Inner
Last


Here is an example :


(8x+9)(2x+5)


Step 1 :First: you have to multiply 8x with 2x which equals to 16x^2


Step 2 : Outer: You have to multuiply 8x with 5 which is going to equal to 40x


Step 3 : Inner : You have to multiply 9 with 2x which gives you 18x.


Step 4 : Last : you have to find the product of 9 and 5 which is 45.


Step 5 : Combine the like terms , in this case it is 40x and 18x . After combineing the terms you should get 58x.


Step 6 : Put the solution in standard form :
16x^2+58x+45 , and thats it youre DONE ! :)
