Question

If
5+23/7+4V3
= a + b/3, then find the values of a and b.
Find the values of a and b:​

Answer 1

Here is ur ans:-

LHS = (5 + 2√3 ) / ( 7 + 4√3 )

rationalize the denominator

= (5 + 2√3 ) ( 7 - 4√3 ) / [ ( 7 + 4√3 ) ( 7 - 4√3 ) 

= [ 5 ×7 - 5 × 4√3 + 2√3 × 7 - 2√3 × 4√3 ] / [ (7 )² - (4√3 )² ]

here we used ( x + y ) (x - y ) = x² - y²  identity

= [35 -20√3 + 14√3 -24 ] / [ 49 - 48 ]

= (11 - 6√3 )

therefore ,

LHS = RHS

11 - 6√3 = A - B√3

comparing both sides

A = 11,

B = 6

Answer 2

if the polynomial ax3 + 3x2- 13 and 2x3-15x +a, when divided by (x-2) leave  the same remainder ,then find the value of a.
