2q%5E3%28-3q%5E4r%29%5E2%2B+-4qr%285q%5E3r%29%5E2%28q%5E4%29








2q%5E3%2A9%2Aq%5E8%2A%28r%29%5E2-4%2Aq%2Ar%2A25%2Aq%5E6%2A%28r%29%5E2%2A%28q%5E4%29





18%2Aq%5E%283%2B8%29%2Ar%5E2-100%2Aq%5E%281%2B6%2B4%29%2Ar%5E%281%2B2%29


18%2Aq%5E%2811%29%2Ar%5E2-100%2Aq%5E%2811%29%2Ar%5E%283%29


2q%5E%2811%29r%5E2%289+-+50r%29 Note: this factoring step is optional (some teachers want this, others don't, so ask your teacher if this is what is wanted)
