11. The values of x and y satisfying the equation

2 (x/a) + y/b = 2 and x/a - y/b = 4 are

Correct Answer: (2) x = 2a y = - 2b
Solution:2ย  x/a + y/b = 2 (i)

x/a - y/b = 4 ....... (ii)

Adding equations (i) and (ii),

(3x)/a = 6

โ‡’x/a = 6/3 = 2

โ‡’ย x = 2a

From equation (i),

2 * (2a)/a + y/b = 2

โ‡’ย y/b = 2 - 4 = - 2

โ‡’y = - 2b

โˆด x = 2aย  ; y = - 2b

20. Solutions of the equation

โˆš3xยฒ+11x+6โˆš3 = 0 are

Correct Answer: (2) -2/โˆš3 , -3โˆš3
Solution:โˆš3xยฒ + 11x + 6โˆš3= 0

โ‡’โˆš3xยฒ + 9x + 2x + 6โˆš3 = 0

โ‡’ โˆš3xย  (x + 3โˆš3) + 2 (x + 3โˆš3) = 0

โ‡’(x + 3โˆš3) (โˆš3x + 2) = 0

โ‡’ x = - 3โˆš3 or, - 2/โˆš3
