Question

Find the value of polynomial p(x)=x³-3x²+1 at x=2​

Answer 1

Answer:

Given :

x = 2

p(x) = x³ - 3x + 1

p(2) = (2) ³ - 3(2) + 1

p(2) = 8 - 6 + 1

p(2) = 8 - 7

p(2) = 1

So the value of the given polynomial is 1.

Answer 2

Answer:

Given - x=2

put x=2 in given equation

∴p(x)=(2)³-3(2)²+1

= 8-3x4+1

= 8-12+1

= 8-13

= -5

∴p(x) = -5
