Expand.(i) ( 5a + 6b)2 (ii) a2 + b32 (iii) 2p - 3q2 (iv) x - 2x

1.	Expand.(i) ( 5a + 6b)2 (ii) a2 + b32 (iii) 2p - 3q2 (iv) x - 2x2(v) ax + by2 (vi) 7m - 42 (vii) x +122 (viii) a - 1a2
Answer» Expand. (i) ( 5a + 6b)² (ii) ${(\frac{a}{2} + \frac{b}{3})}^{2}$ (iii) ${(2 p - 3 q)}^{2}$ (iv) ${(x - \frac{2}{x})}^{2}$ (v) ${(a x + b y)}^{2}$ (vi) ${(7 m - 4)}^{2}$ (vii) ${(x + \frac{1}{2})}^{2}$ (viii) ${(a - \frac{1}{a})}^{2}$
