Factoring a=1

Factoring a=1

SWBAT factor trinomials when a=1.

What is a trinomial?

Multiple Choice

 $ax^2+bx+c$  What do a and b represent in a quadratic trinomial?

• Constants

• Coefficients

• Variables

Multiple Choice

 $\left(3x-2\right)\left(x+1\right)$  Foil/Expand the following:

•  $4x-1$  

•  $3x^2+3x+2x-1$  

•  $3x^2+x-2$  

Factoring is just the opposite of foiling

• When we foil, we want to get rid of the parentheses.

• When we factor, we're bringing back the parentheses.

• Both forms are helpful when analyzing quadratics.
