Exercise 2.2
1. Classify into like terms:
4x?, 51, -81", xy, 6x", 4v, - 74.x", 8ry, 7xyz, 3x”.
2. Simplify:
(i) 73 - 9y+3 - 3x - 5y + 8; (ii) 3x +517 - 4y + x - 8vy - 5y?
3. Add:
(1) 5a +3b, a - 2b and 3a +5b; (ii) xi-xy+51 +), 7-91 ty, and 3x+y+ 9xy'.
4. Subtract:
(i) -20 + 3xy from 8ry; (ii) a - b-2c from 4a + ob - 2c.
Multiplication of Polynomials
Observe the following products: (i) 5v 61*= (5 x 0)*(1 * x ) = 30x';
(ii) 2x x 67 8z = (2x * Ov) * (82)
= ((2x 0)* (*)) (82) = (120v) (82)
= (12*8) * (1) * 2) = 96xyz.
