Question

form the give information find which between the other two d(p,r)=7 d(p,q)=10 d (q,r)=3​

Answer 1

Answer:

Given x3 -2x2y + 3xy2– y3, 2x3– 5xy2 + 3x2y – 4y3 Collecting positive and negative like terms together, we get = x3 +2x3 – 2x2y + 3x2y + 3xy2 – 5xy2 – y3– 4y3 = 3x3 + x2y – 2xy2 – 5y3 (ii) Given a4 – 2a3b + 3ab3 + 4a2b2 + 3b4, – 2a4 – 5ab3 + 7a3b – 6a2b2 + b4 = a4 – 2a3b + 3ab3 + 4a2b2 + 3b4 – 2a4 – 5ab3 + 7a3b – 6a2b2 + b4 Collecting positive and negative like terms together, we get = a4 – 2a4– 2a3b + 7a3b
