Today our class worked Substitution we first started with easy ones then we started with some like this...
A= 3x+4
B=2x-5
C=4x+1
(A+B)(B-C)
(3x+4+(2x-5)) (2x-5-(4x+1))
=(3x+4+2x-5) (2x-5-4x-1)
= (5x-1) (-2x-6)
= -10x^2-30x+2x+6
= -10^2-28x+6
algebras can be very tricky so this is what we did today in our math class.

Nice work Amanda. Can you choose the scribe for next class?
