Question

find the quadritic polynomial ,sum and product of zeroes are 2,-1​

Answer 1

Step-by-step explanation:

Let A and B be the zeroes of the quadratic polynomial

so A+B = 2/1=-b/a =sum of zeroes

and A*B =-1/1=c/a = product of zeroes

so therefore

a=1

b=-2

c=-1

so we know that ax²+bx+c is a gereneal form of a quadratic equation

so by putting values of a,b,c

x²-2x-1

Thank you
