white each quadratic equation in the standard form ax²+bx+c= 0, and identify a, b, and c.

1. (3x-1)(2x+1)=4
2. x² =8
3. 5x=x²

1.(3x-1)(2x+1)=4
6x^2+3x-2x-1=4
6x^2+x-5=0

a=6 b=1 c=-5

2.x^2=8
x^2-8=0

a=1 b=0 c=-8

3.5x=x^2
0=x^2-5x

a=1 b=-5 c=0

1.    = 6x²+3x-2-1=4
       =6x²+x-1-4=0
       =6x²+x-5=0
    A=6 B=1 C=-5
2.     x²-8=0
    A=1 B=0 C=-8
3.        x²+5x=0
   A=1 B=5 C=0
