Question

If u(x) = x5 – x4 + x2 and v(x) = –x2, which expression is equivalent to (U divided by V) (x)

Answer 1

\[u(x)=x ^{5}-x ^{4}+x ^{2}\]
and\[v(x)=-x^{2}\]

Factor \[u(x) = x ^{2}(x ^{3}-x ^{2}+1)\].
(Notice that this is an application of the distributive property.)

You can write the division like this so that it looks more familiar:
\[\frac{ u(x) }{ v(x) } = - \frac{ x ^{2}( x ^{3}-x ^{2}+1) }{ x ^{2} }\]

The x-squareds in the numerator and denominator 'cancel', leaving the expression in the numerator.

Answer 2

a.x3 – x2
b.–x3 + x2
c.–x3 + x2 – 1
d.x3 – x2 + 1

Answer 3

you see why I need help don't understand it

Answer 4

OK. Do you understand what I wrote?
