Question

7x⁴_2x³+x+10; 3x⁴+15x³+9x²_8x+2

Answer 1

Answer:

i. (7x4 – 2x3 + x + 10) + (3x4 + 15x3 + 9x2 – 8x + 2) = 7x4 – 2x3 + x + 10 + 3x4 + 15x3 + 9x2 – 8x + 2 = 7x4 + 3x4 – 2x3 + 15x3 + 9x2 + x – 8x + 10 + 2 = 10x4 + 13x3 + 9x2 – 7x + 12 ii. (3p3q + 2p2q + 7) + (2p2q + 4pq – 2p3q) = 3p3q + 2p2q + 7 + 2p2q + 4pq – 2p3q = 3p3q – 2p3q + 2p2q + 2p2q + 4pq + 7 = p3q + 4p2q + 4pq + 7Read more on Sarthaks.com - https://www.sarthaks.com/847008/add-the-following-polynomials-i-7x-4-2x-3-x-10-3x-4-15x-3-9x-2-8x-2
