Question

6. Verify if -3 and 4 are zeroes of the polynomial 2x2 – 3x2-23x + 12. If yes, then factorise the
polynomial.​

Answer 1

Answer:

No

Explanation:

We have , 3x2-23x+12

=3(-3)2-23(-3)+12

=27+69+12

=108

so (-3)is not a zero of this polynomial

Again ,3(4)2-23(4)+12

=48-92+12

=-32

so 4 is not a zero if this polynomial
