Question

Q10. The number of
polynomials having zeroes as –
1 and 3 is *
1
2
3
many​

Answer 1

Answer:

The answer is many

and there are infinite

Answer 2

Answer:

d.more than three

Step-by-step explanation:

let the required quadratic polinomial be f(x)=-b/a

sum of the zeros =-b/a

2+1=-b/a

3=-b/a

3/1=-b/a

• °• b=-3 and a=1

product of zeros =c/a

2×1=c/a

2=c/a

c=2

so,the equation is f(x)=x2-3x+2

[we known that zeros does not change if the polinomial is divided or multiplied constant]

f(x)=kx2-kx+2k[where k is real number]

f(x)=(x2/k)-(3/k)x+(2/k)

{k is a non- zero real number}

therefore,there are infinitely many polinomials...

i.e more than 3
