Question

P(x) = x³+3x²-5x+8 then the value of p(2)_

Answer 1

Answer:

p ( 2 ) = 18

Step-by-step explanation:

p ( x ) = x^3 + 3x^2 - 5x + 8

Hence,

p ( 2 ) = ( 2 )^3 + 3 ( 2 )^2 - 5 ( 2 ) + 8

p ( 2 ) = 8 + 3 ( 4 ) - 10 + 8

p ( 2 ) = 8 + 12 - 10 + 8

p ( 2 ) = 18

Answer 2

Hi there✌✌✌✌

Substitute x=2,we get-


${2}^{3} + 3 \times {2}^{2} - 5 \times 2 + 8$

$= 8 + 12 - 10 + 8$

$= 18$
