Q. 1 B

Find the values o

Answer :

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


x = -3


put x = 3 in 2x3 – 13x2 + 17x + 12


2(-3)3 – 13(-3)2 + 17(-3) + 12


2(-27) – 13(9) + (-51) + 12


- 54 – 117 – 51 + 12


- 171 – 51 + 12


- 222 + 12


-210


Hence value of 2x3 – 13x2 + 17x + 12 at x = -3 is -210
