Question

1. If a and B are the zeroes of polynomial x2 - 2x - 8 then form a quadratic polynomial
whose zeroes are 3a and 3B.​

Answer 1

Answer:

x²-6x-72.

Step-by-step explanation:

Here, sum of zeroes , x+y=2

& product of zeroes, xy= -8

then, a=4 &b=-2

So, 3a=12 & 3b= -6

Then , the sum of zeroes, x+y=6

& the product of zeroes,xy= -72.

Then, the polynomial will be x²-6x-72.
