denominator in the second fraction is the first denominator squared... (3x/x1)  (x4/x^22x+1) = (3x/x1)  (x4/(x  1)^2) Thus we will need to multiply the first fraction by (x  1) / (x  1)... (3x(x  1)/(x  1)^2)  (x4/(x  1)^2) and put it all over the same denominator: [(3x(x  1)  (x  4)] / (x  1)^2 Now expand the numerator and simplify... [(3x(x  1)  (x  4)] / (x  1)^2 = (3x^2  3x  x + 4) / (x  1)^2 = (3x^2  4x + 4) / (x  1)^2 Nothing more can be done with this one...that's the answer.

\[\frac{\frac{4}{x}+\frac{7}{x^{2}}}{\frac{16}{x^{2}}\frac{49}{x}}\]first simplify numerator: \[\frac{4}{x}+\frac{7}{x^{2}}=\frac{4x+7}{x^{2}}\]next simplify the denominator: \[\frac{16}{x^{2}}\frac{49}{x}=\frac{1649x}{x^{2}}\]now use the following rule for fraction division:\[\frac{a}{b}/\frac{c}{d}=\frac{a}{b}*\frac{d}{c}\]and you will get: \[\frac{\frac{4}{x}+\frac{7}{x^{2}}}{\frac{16}{x^{2}}\frac{49}{x}}=\frac{4x+7}{x^{2}}/\frac{1649x}{x^{2}}=\frac{4x+7}{x^{2}}*\frac{x^{2}}{1649x}\]\[=\frac{4x+7}{1649x}\]

for question 9, a polynomial is defined as:\[c_0x^{0}+c_1x^{1}+c_2x^{2}+...+c_nx^{n}\] all the "c" terms are constants. it's "degree" is defined as the highest "power" of x that you have  in the case above it is a polynomial of degree "n". e.g. 2x+9x^2 is a polynomial of degree 2. you should be able to answer question 9 with this information.

correct  the only term given in the polynomial in question 9 is\[2\pi\]which is just a constant. so there are no powers of x in this.

I am not looking for a medal  I am here to try and you understand maths. If you are not interested in maths then I guess there is no point in me trying to explain it to you.

I can try and teach you how to solve these yourself. you may think its very complicated but it is fairly straight forward and it will give you greater satisfaction when you know that you can work these out yourself. I am not looking for any money or medals. Let me know if you wish to learn.

Yes...but it is very dificult...
 2 years ago

asnaseerBest ResponseYou've already chosen the best response.1
ok  the answer here is 3 because the term with the highest power is "100x^3". you only need to look at the powers of x  you can completely ignore the coefficients (i.e. ignore the 100 which x^3 is multiplied by)

lets try one more: what is the degree of this polynomial?\[99+3x\]
 2 years ago

asnaseerBest ResponseYou've already chosen the best response.1
the answer is "1" because the highest power of x here is in the term "3x".\[x = x^1\] similarly, the polynomial: 123 has a degree of "0" because if has no "x"'s in it  just a constant. you should now be able to answer question 9.
