12 over 5 w squared

15w4


Simplify completely quantity x squared minus 4 x plus 4 over quantity x squared plus 10 x plus 25 times quantity x plus 5 over quantity x squared plus 3 x minus 10

quantity x minus 2 over quantity x plus 5

x minus 2 all over the quantity x plus 5 end quantity squared

the quantity x minus 2end quantity squared all over x plus 5

Answer 1

\[\frac{\frac{25w^6}{10w^3}}{\frac{30w^2}{5w}}\]Is that the first expression?

I would first do the fraction division, by multiplying the top half by the reciprocal of the bottom half:
\[\frac{25w^6}{10w^3}*\frac{5w}{30w^2}\]Then use the rules of exponents to simplify, in particular \[\frac{x^n}{x^m} = x^{n-m}\]
