Q1.Thnx dedo pleach QUESTION: if p=4,q=3,andr= -2,then find the value of the algebraic expression p²+q²-r² ———— pq+qr-pr About the author Arya
Answer: Agar aapne mere question report kare toh aapko paap lagega ._. [tex](p + q + r {)}^{2} = {p}^{2} + {q}^{2} + {r}^{2} + 2pq + 2qr + 2rp \\ \\ = (4 {)}^{2} + (3 {)}^{2} + ( – 2 {)}^{2} + 2(12) + 2( – 6) + 2( – 8) \\ \\ = 16 + 9 + 4 + 24 – 12 – 16 \\ \\ = 12 + 9 + 4 \\ \\ = 16 + 9 \\ \\ = 25[/tex] Reply
