Question

Please help me multiply this rational expression:
8x/-1 * 1/4x^2

Answer 1

is it really
\[\huge \frac{8x}{-1}\times \frac{1}{4x^2}\]?

Answer 2

usually you do not right "divided by -1"
you would see instead
\[-8x\times \frac{1}{4x^2}\] or
\[\frac{-8x}{4x^2}\]

Answer 3

cancelling gives you
\[-\frac{2}{x}\]

Answer 4

Okay great, could you help me with this one as well @satellite73 ?
\[\frac{ 4s }{ 3t } x \frac{ 9s^2 }{ -4 }\]
