Question 167621
2. Correct.
.
.
6. Incorrect. Exponents are correct, coefficients are not.
{{{(6y^4-3y^3+18y^2)/(9y^2)=(6y^4)/(9y^2)-(3y^3)/(9y^2)+(18y^2)/(9y^2)}}}
{{{(6y^4-3y^3+18y^2)/(9y^2)=(6y^2)/(9)-(3y)/(9)+(18)/(9)}}}
Reduce to lowest terms.
.
.
14.) Incorrect: {{{(x+3)(x+2)=x^2+5x+6}}},
Should be {{{x-3}}}
 {{{(x-3)(x+2)=x^2-x-6}}}
.
.
20.) Incorrect, your first term should be an {{{x^2}}} term. 
Use synthetic division. 
I'll do it for this one and you can do it for the next two.
.
.
.
Showing synthetic division is a little difficult.
The first part will show the factor (left hand column), then the factor times the divisor,
then the next line will show the subtraction.
Repeat.
Hopefully it makes sense.
The {{{0x^2}}} and {{{0x}}} term are there as placeholders.
