These are binomials:
* means multiply
(2*3) (4*8)
(4*6) (x*3)
(x*84) (48.5*3)
How to solve>
use the F.O.I.L. meathod
1) F stand for First (multiply the first number/variable in each set of parenthases to each other)
2) O stands for Outer (multiply the 2 outer most number/variables in the problem together)
3) I stands for Inner (multiply the 2 number/variable on the inside of the problem to each other)
4) L stands for Last ( -- )
ex: (3*x) (5*7)
1) 3*5=15
2) 3*7=21
3) x*5=5x
4)x*7=7X
^^ multiply the answers you got to each other in that order-
you get; 15*21*5x*7x
then multiply the like terms-
15*21= 315
5x*7x=35x
the answer is "315*35x"

The advantage of recognizing some special binomials is that the math can then be done much more quickly. Some of the binomials appear very frequently.
Explain how I would use algebra times to multiply two binomials (FOIL)?
It's the difference between multiplication and division. Multiplying binomials is combining them. Factoring polynomials is breaking them apart.
