multiplying binomial to binomial

Sagot :

To multiply binomial to binomial, use the foil method:

Example:
(x+2)(2x+3)

It can be written as:
x(2x+3)+2(2x+3)
2x²+3x+4x+6
Add all like terms
2x²+7x+6

Hope this helps =)
[tex]multiplying\ a\ binomial\ to\ a\ binomial\ is\ the\ second\ step\ of\ knowing \\ the\ elementary\ algebra:) \\ \\ I\ give\ you\ an\ example\ of\ it;(Hope\ you\ like\ it) \\ \\ (3x+2)(5x+3) \\ \\ Use\ the\ FOIL\ Method\ to\ find\ the\ product:) \\ \\ First;(3x)(5x)=15x^{2} \\ Outer;(3x)(3)=9x \\ Inner;(2)(5x)=10x \\ Last;(2)(3)=6 \\ \\ 15 x^{2} +9x+10x+6 \to \boxed{15 x^{2} +19x+6} \\ \\ Hope\ you\ like\ it:) \\ Domini[/tex]
