If p(x)=2x2-5√3+5 then p(5√3).

Put x = 5√3 in the given polynomialp(5√3) = 2×(5√3)2 – 5√3 × 5√3 + 5= 2 × 25 × 3 – 25 × 3 + 5= 150 – 75 + 5p (5√3) = 80

Q13 of 84 Page 53

If p(x)=2x²-5√3+5 then p(5√3).

Put x = 5√3 in the given polynomial

p(5√3) = 2×(5√3)² – 5√3 × 5√3 + 5

= 2 × 25 × 3 – 25 × 3 + 5

= 150 – 75 + 5

p (5√3) = 80
