Find the values of the polynomial 2x3 – 13x2 + 17x + 12 at the following values of x.

x = 2

Answer :

Substitute the given values of x in 2x3 – 13x2 + 17x + 12 to find value of polynomial


x = 2


put x = 2 in 2x3 – 13x2 + 17x + 12


2(2)3 – 13(2)2 + 17(2) + 12


2(8) – 13(4) + 34 + 12


16 – 52 + 46


16 – 6


10


Hence value of 2x3 – 13x2 + 17x + 12 at x = 2 is 10
