Question

16. If the product of the zeroes of the polynomial ax -6x-6 is 4, then find the value of a.
Also find the sum of zeroes of the polynomial.​

Answer 1

aײ-6×-6=0

For a quadratic polynomial;

product of its zeroes=c/a

=)4=-6/a

=)a=-3/2=-1.5

● sum of zeroes of a quadratic polynomial= -b/a

=)sum=6/-1.5

=)sum=-4
