The solution set of 'Ax-3 +-/2x + 3 = 6 is :(i) 37,9(iii) 3,9d)(ii) 11

1.	The solution set of 'Ax-3 +-/2x + 3 = 6 is :(i) 37,9(iii) 3,9d)(ii) 111, 3(iv) none of these
Answer» Squaring both sides,(√(4x-3)+√(2x+3))²=36 Using identity (a+b)²=a²+b²+2ab 4x-3+2x+3+(2√(4x-3)√(2x+3))=366x+(2√(8x²+12x-6x-9))=366x+(2√(8x²+6x-9))=36Therefore, x=3,9(By putting value x=3,9 in LHS) wrong

The solution set of 'Ax-3 +-/2x + 3 = 6 is :(i) 37,9(iii) 3,9d)(ii) 111, 3(iv) none of these

Answer»

Squaring both sides,(√(4x-3)+√(2x+3))²=36

Using identity (a+b)²=a²+b²+2ab

4x-3+2x+3+(2*√(4x-3)*√(2x+3))=366x+(2*√(8x²+12x-6x-9))=366x+(2*√(8x²+6x-9))=36Therefore, x=3,9(By putting value x=3,9 in LHS)

wrong
