$\"10p%5E2c%5E2+%2B+7pcr+=+12r%5E2\"$ Solve for r
\n" ); document.write( "-------------------
\n" ); document.write( " $\"12r%5E2+-+%287pc%29r+-+10p%5E2c%5E2+=+0\"$
\n" ); document.write( "Factor it
\n" ); document.write( "(4r - 5pc)*(3r + 2pc) = 0
\n" ); document.write( "r = 5pc/4
\n" ); document.write( "r = -2pc/3\r
