Re: review
Since you are subtracting you are taking them away from zero.
1 0 0 7
- 9 5 2
-------------
You do not just bring the 9 and the 5 down, do you? You subtract them from zero. There are no empty columns!

Re: review
oooooooooooh ok yeah that explains it much much better thanx
so 5x^4 - 2x^4= 3x^4
0--3x^3=3x^3
-3x^2-0=-3x^2
7x-6x=1x
-10--17=7

Hi;
When writing 1x it is okay to leave out the 1. 1x = x

Re: review
yup this is 7
7. Multiply 9x^3(4x + 7)
7-
9x^3*4x+9x^3*7
36x^3+63x^3= (99x^6)

Re: review
thank you bobbym
this is the next one hope its correct
8. Multiply (3x 1)(5x 9)
8- (3x*5x)-(3x*-9)-(-1*5)-(-1*-9)
(15x^2-27x-5x+9)
(15x^2-32x+9)

Re: review
11-Factor 32x^3 32x^2 + 8x by first finding the GCF, then factor the quadratic that is left. Be sure to factor completely and show your work. If this is not possible for some reason, state why.
11- 32x^3-32x^2+8x
Gcf=8x
8x(4x^2-4x+1)
12- Factor x^2 + 9x + 14 by grouping. Be sure to factor completely and show your work. If this is not possible for some reason, state why.
12- x^2+9x+14
X^2*14=14x : 7*2
X^2+7x+2x+14
X(x+7)+2(x+7)
(x+2)(x+7)
