A. Write the quadratic equations in standard form, ax2+bx+c=0. Then
identify the values of a, b and c
1. 2×2+9x=10
Standard Form:
ar_____b=
c=
2. x2+x=-2
Standard Form:
a=
_b
3. 3×2+9=10x Standard Form:
a=
b=
4. 6x-2×2 =4
Standard Form:
b=
5. x(2x-7)= 8
Standard Form:
a=
b=
c=

Answer:
1. 2x²+9x-10=0 a= 2; b= 9; c= -10
2. x²+x+2=0 a=1; b=1;c=2
3.3x²-10x+9=0 a=3;b= -10;c=9
4.2x²+6x-4=0 a=2; b=6; c=-4
5.2x²-7x-8=0 a=2; b= -7;c= -8
