Question 1126796
<pre>
In case you just want the answers, and not how to get them, 
just to fool your teacher into thinking you know how to do them, 
here they are:

{{{64 - 96x + 60x^2 - 20x^3  + expr(15/4)x^4 - expr(3/8)x^5 + expr(1/64)x^6}}}

6a^2x^2 + 4ax + 4bx^2 + 1

1 + (6a^2+4b)x^2 + 6a^2x^2

{{{1 + (6a^2+4b)x^2 + 6a^2x^2+"..."}}} since these are {{{1+8x+12x^2}}}

then  {{{system(1=1,6a^2+4b=8,6b^2=12)}}}

Simplifying:

{{{system(3a^2+2b=4,b^2=2)}}}

{{{b=sqrt(2)}}}

{{{matrix(6,1,

3a^2+2b=4,
3a^2+2sqrt(2)=4,
3a^2=4-2sqrt(2),
a^2=(4-2sqrt(2))/3,
a = "" +- sqrt((4-2sqrt(2))/3),
a = expr(1/3)sqrt(6(2 - sqrt(2)))
 )}}}

But if you want to know how to get these answers then ask me
in the space below, and I'll get back to you by email
