Given polynomial:

Product of zeroes of this polynomial = 4.

A polynomial is an expression of more than one or two algebraic term, may be a sum of those terms also.

We know, that the product of zeroes of a polynomial can be given by =c/a

Hence, for the polynomial: , a = a, b = -6 and c = -6.

Product of zeroes of this polynomial = (-6)/a

4 = -6/a

a = -6/4= -3/2

Here x is equal to 4 . Put the value 4 in the place of X. a(4×4)-6(4)-6=0. 16a-24-6=0. 16a = 30 . a= 15/8. I think it is clear to u.
