Question

show that 3 is zero of polynomial 2X3-X2-13X-6

Answer 1

hiiiii friend!!!!!!

here is urs answer :⇒

⇒  2x^3 - x^2 - 13x - 6

⇒ 2 (3)^3 - (3)^2 - 13 (3) - 6

⇒ 2 (27) - 9 - 39 - 6
⇒ 54 - 48 - 6

⇒54 - 54

⇒ 0

i hope it may help u!!!!!!

Answer 2

2(3)3-(3)2-13(3)-6 = 2(27)-9-39-6

=54-54= 0

therefore 3 is a zero of the polynomial.if 3 is a zero then (x-3) is a factor.

we have to divide 2x3-x2-13x-6 by (x-3)


Hope its help you dear
