Today in class we continued to learn about multiplying polynomials.

Ex.

2x(3x+7) = (2 x 3 x) + ( 2 x 7 ) This is called distributive property.

= (2 3 x x) + (2 7 x) You then put the like terms together.

= 6x^2 + 14x Then you simply multiply the terms to get your answer.

Here is another example of multiplying polynomials

-2x(3x+2y-1) = ( -2 x 3 x ) + ( -2 x 2 y) + ( -2 x -1)

= ( -2 3 x x ) + ( -2 2 x y ) + ( -2 -1 x )

= -6x^2 +( -4xy) + 2x

= -6x^2 -4xy + 2x

After that the teacher showed us how to model equations.

This equation is 3x (2x+1)

The lone number is the number you multiply by and the 2 numbers are the numbers being multiplied.

This is our homework.
