Answer:
The value of a polynomial obtained on putting a particular value of the variable is called the value of the polynomial.
(i) p(x) = 5x – 4x² + 3
On putting x = 0 ,
p(0) = 5(0) – 4(0)² + 3
= 0 – 0 + 3
=3
p(0) = 3
(ii) p(x) = 5x – 4x² + 3
On putting x= -1,
p(-1) = 5(-1) – 4(-1)²+ 3
= -5 – 4(1) + 3
= -5 – 4 + 3
= -9 + 3
= -6
p(-1) = -6
(iii) p(x) = 5x – 4x² + 3
On putting x = 2
p(2) = 5(2) – 4(2)² + 3
= 10 – 16 + 3
= -6 + 3
p(2) = -3
