Question

find a quadratic polynomial whose sum of zeroes and product of zeroes are given respectively (-2√3),-9 also find their zeroes ​

Answer 1

Step-by-step explanation:

Let m , n are two zeroes of a quadratic

polynomial ,

It is given that

sum of the zeroes = m + n = -2³ = -8

product of the zeroes = mn = -9

Now , form of a quadratic polynomial whose

zeroes are m , n is

p ( x ) = x² - ( m + n )x + mn

= x² - ( -8 )x + ( -9 )

= x² + 8x - 9
