%28v%5E2%2Bv-1%29%28v%5E2%2B5v-7%29 Start with the given expression.


v%5E2%28v%5E2%2B5v-7%29%2Bv%28v%5E2%2B5v-7%29-1%28v%5E2%2B5v-7%29 Expand. Remember that %28A%2BB%2BC%29%28D%2BE%2BF%29=A%28D%2BE%2BF%29%2BB%28D%2BE%2BF%29%2BC%28D%2BE%2BF%29


Distribute.


v%5E4%2B5%2Av%5E3-7%2Av%5E2%2Bv%5E3%2B5%2Av%5E2-7%2Av-v%5E2-5%2Av%2B7 Multiply.


v%5E4%2B6%2Av%5E3-3%2Av%5E2-12%2Av%2B7 Now combine like terms.


So %28v%5E2%2Bv-1%29%28v%5E2%2B5v-7%29 expands to v%5E4%2B6%2Av%5E3-3%2Av%5E2-12%2Av%2B7.


In other words, %28v%5E2%2Bv-1%29%28v%5E2%2B5v-7%29=v%5E4%2B6%2Av%5E3-3%2Av%5E2-12%2Av%2B7.
