Question

factorise p^2q-pr^2-pq+r^2 ?

Answer 1

☆Hello friend☆

${p}^{2} q - p {r}^{2} - pq + {r}^{2} \\ {p}^{2} q - pq - p {r}^{2} + {r}^{2} \\ p(pq - q) - r(pr - r)$

Its can solve till here, Hope it helps☺!

Answer 2

Answer:

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

Step-by-step explanation:

p^2q - pr^2 - pq + r^2

p^2 - pq - pr^2 + r2

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

(pq - r^2) (p  - 1)
