Question

If p(r) = r²-(4+√3)r +4√3 then p (√3) =​

Answer 1

$\sf\huge\bold{Answer:}$

Given :

p(r) = r²-(4+√3)r +4√3

To find :

p (√3)

Solution :

⟶ p(r) = r²-(4+√3)r +4√3

$\fbox{When [ r = √3 ]}$

⟶p(√3) = √3²-(4+√3) √3 +4√3

⟶p(√3) = 3 -(4+√3)√3 +4√3

⟶p(√3) = 3-(4√3+3)+4√3

⟶p(√3) = 3-4√3-3+4√3

⟶p(√3) = 3-3-4√3+4√3

⟶p(√3) = 0

Hence, p(√3) = 0

Answer 2

Answer:

Here is your answer mate,

Step-by-step explanation:

p(r) = r²-(4+√3)r +4√3 --- eq 1

p (√3) =?

Given ,

r = √3

Substituting r = √3 in equation 1

p (√3) = (√3)² - (4+√3)√3 + 4√3

p (√3) = 3 - 4√3 - √3×√3 + 4√3

= 3 - 4√3 - (√3)² + 4√3

= 3 - 3 - 4√3 +4√3

= 0

p (√3) = 0
