Question

If the product of zeroes of a polynomial ax2-6x-6 is 4 ,then find value of a also find sum of zeroes of polynomial

Answer 1

Step-by-step explanation:

here

The first term is,  ax2  its coefficient is  a .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -6 .

αβ =c/a.

αβ = 4 .(given).

so,c/a =4

-6/a=4/1

(cross multiplication)

-6×1 = 4×a

4a = -6

a =-6/4

a= -3/2.

we know sum of zeroes (α+β) = -b/a .

-b/a = -(-6)/[ -3/2]

+6×[2/-3].

12/-3

=》-4

therefore (α+β) = -4. & a = -3/2.
