Question

Qn 18 answer in paper pls​

Answer 1

Answer:

Step-by-step explanation:

Given:α and β are zeroes of polynomial x^2-2x-15.

Therefore, sum of zeroes =α=-b/a

=2/1=2

And product of zeroes =c/a= -15*1=-15

So, zeroes are 2 or -15.

Now new zeroes = 2*2=4

And 2*-15=-30

We know that any quadratic equations is of the form x^2-(α+β)x+αβ

So, = x^2-(2)x+(-30)

= x^2-2x-30 is required quadratic equation. Hope it will help.... pls mark it as brainliest.
