IIIA Math Formals

These Math Formals will be used as a reminder on how to solve using them.

Formals from Unit 1:

Ax^2+bx+c

Guess and Check

(dx+e)(fx+g)

Ax^2+bx+c=0

Guess and Check

(dx+e)(fx+g)=0

(dx+e)=0 (fx+g)=0 dx= -e fx = -g x= -e/d x= -g/f

Ax^2+bx+c=y

(Ax^2+bx+ ) = y -c

(Ax^2+bx+d)-d = y -c

Guess and Check

(Ex+f)(Ex+f)-d=y-c

y=(Ex+f)^2-d+c

y=(Ex+f)^2+G
