sum of zeroes = -b/a. = -(-5)/a. =10
then. ,5=10a
a. = 5/10= 1/2
now product of zeroes. =c/a= 10
c/1/2=. 10..............( putting a=1/2 )
now 2c=10
c=10/2
c. = 5

Answer:
The value of a is and value of c is 5
Step-by-step explanation:
Explanation:
Given , a polynomial whose,
sum and product of zeroes are equal to 10 each .
Let be the zeroes of the given polynomial .
Step 1:
As we know that , sum of zeroes of the polynomials is
⇒ = = =
⇒ = 10 (Given )
⇒a =
And the product of the zeroes
⇒ = ........(i)
Now put the value of a = in (i) we get
which is equal to 10 .
⇒2c = 10 ⇒ c = 5
Final answer :
Hence , the value of a is and value of c is 5
