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

x = -1

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


x = -1


Put x = - 1 in 2x3 – 13x2 + 17x + 12


⇒ 2(-1)3 – 13(-1)2 + 17(-1) + 12


⇒ 2(-1) – 13(1) – 17 + 12


⇒ - 2 – 13 – 17 + 12


⇒ - 15 – 17 + 12


⇒ - 32 + 12


⇒ -20


Hence value of 2x3 – 13x2 + 17x + 12 at x = -1 is -20
