Question

7. Find a quadratic polynomial whose zeroes
are 15 and -V15. [CBSE 2012]
​

Answer 1

Answer: x^2-(x)×0-225

Step-by-step explanation:

# So it is given that the zeros are...

15 and (-15)

And we also know that the the formula of forming quard. Equeation is:- x^2-Sx+P.............................(1)

Where S = sum of zeros

And P = product of zeros

So therefore....

Sum of the product:- 15+(-15)

15-15=0

And,product:-15×(-15)=(-225)

So; putting the value of.....S and P in (1) equeation..

So, there fore the answer is......

x^2-225

So.....
