Question

if p(x)=x^2-3√3x+5 find the value of p(2√3)


plz give the answer with solution​

Answer 1

Answer:

Given that,

P(x) = x^2 - 3 ( √3x ) + 5

Substituting 2√3 in P( x )

That is substitute 2√3 in place of x.

P ( 2√3 ) = (2√3)^2 - 3 ( √3 * 2 √3 ) + 5

= (4 * 3) - (6 * √3 * √3 ) + 5

= 12 - (6 * 3) + 5 = 12 - 18 + 5 = -1

P(2√3) = -1
