Answer» (i) योगफल = (3x2 + 5x – 2) + (-3x2 – 5x + 6) = 4 (ii) योगफल = (3x2 – 7x + 5) + (6x3 + 5x – 7) = 6x3 + 3x2 – 2x – 2 (iii) योगफल = (x2 + x -7) + (x3 + x2 + 3x + 4) = x3 + 2x2 + 4x – 3 (iv) योगफल = (x3 – 5x2 + x + 2) + (x3 – 3x2 + 2x + 1) = 2x3 – 8x2 + 3x + 3 (v) योगफल = (x6 – 3x4) + (x4 + x3 + 2x2 – 6) = x6 – 2x4 + x3 + 2x2 – 6 |
