Pq(r²-1)-r(p²+q²) factorize​

pqr2-pq-p2r-rq2 is the answer

Step-by-step explanation:

pq(r^2 - 1) - r(p^2 + q^2)

multiply the brackets

=pq*r^2 - pq*1 - r*p^2 - r*q^2

=pqr^2 - pq - rp^2 - rq^2

=pqr^2 -rp^2 -rq^2 -pq

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
