Multiplication in Algebra - Binomial multiplication with two tribes -
Still the same as the previous multiplication. Binomial multiplication with two tribes still use the distributive properties.What is the nature of the distributive ? You can click here for know about distributive. Binomial multiplication with two tribes you can see this picture below :
From the picture we can draw conclusions :
( a + b ) ( c + d ) = ( a x c ) + ( a x d ) + (b x c ) + ( b
x d )
= ac +
ad + bc
+ bd
Example :
( 2x + 3y ) ( x + 2 y ) = ( 2x . x ) + ( 2x . 2y ) + ( 3y . x ) + ( 3y . 2y)
= 2x2 + ( 2 . 2 . x . y ) + 3yx + ( 3 . 2 . y . y )
= 2x2 + 4xy + 3xy + 6y2
