Question

Find the value of the polynomial p(z) = 3z^2 - 4z + root 17 when z = 3

Answer 1

z = 3

fill value 3 instead of z

p(z) = 3z²-4z+√17

p(3) = 3(3)²-4(3)+√17

p(3) = 3(9) -12 +√17

p(3) = 27 - 12 +√17

p(3) = 15 + √17

Answer 2

solution

Given value of z= 3

putting the value of z in Polynomial.

3(3)^2- 4(3)+ √17

= 27 -12 + √17

= 15 + √17
