You can put this solution on YOUR website!
The key to multiplying rational expressions is to factor and cancel. I think you meant to solve:
\n" ); document.write( "(3x-30)/(x^2-4x)*(8x)/(10-x)
\n" ); document.write( "(3(x-10))/(x(x-4))*(8x)/(-1(-10+x)) Factor the numerators and denominators.
\n" ); document.write( "(3(x-10))/(x(x-4))*(8x)/(-1(x-10))
\n" ); document.write( "(24x(x-10))/(-x(x-4)(x-10)) Multiply numerators times numerators and denominators times denominators.
\n" ); document.write( "-24/(x-4) Cancel any numerators and denominators that match. \n" ); document.write( "
