Subtract `3pq(p-q)` from `2pq(p+q)`

Subtract 3pq(p-q)0m2pq(p+q)

Subtract : - 3p ^(2) + 3pq +3p x from 3p (- p -a - r)

Subtract: 4pq - 5a^(2) - 3p^(2) "from" 5p^(2) + 3q^(2) - pq

(a) Subtract 4a-7ab+3b+12 from 12a-9ab+5b(r) Subtract 3xy+5yz-7zx from 5xy-2yx+10xyz( ij ) Subtract 4p^(2)q-3pq+5pq^(2)-8p+7q-10 from 18-3p-11q+5pq-2pq^(2)+5p^(2)q

Verify that (p-q) ( p ^(2) + pq + q ^(2)) = p ^(3) - q ^(3)

If the equation x^(2)+px+q=0 and x^(2)+p'x+q'=0 have a common root show that it must be equal to (pq'-p'q)/(q-q') or (q-q')/(p'-p)

pq ^(2) + q (p -1) -1= ?
