Question

if the product of zeroes of the polynomial ax2-6x-6 is 4 find the value of a and find the sum if zeroes of the polynomial​

Answer 1

Answer:

Step-by-step explanation:

Let p(x)=ax^2-6x-6

Since 4 is the zeros of the p(x)

So p(4)=a(4)^2-6×4-6=0

16a-24-6=0

16a-30=0

a=30/16=15/8

Sum of zeros= -(coefficient of x^2)/constant term

=. -a/-6

=a/6

=15/8×1/6 (a=15/8)

=15/48

=5/16
