Question

find the quadratic polynomial, sum and product of whose zeroes are 2 and -1 respectively​

Answer 1

Answer:

x2 -2x-1=0

Step-by-step explanation:

 Alpha+ Beta= -b/a=2

 alpha*Beta= c/a =-1

 Now, Let a=1,b=-2 and c=-1

     so , the quadratic polynomial be

                          x2-2x-1 =0

Answer 2

Answer:

given

alpha + beeta = 2

alpha×beeta= 1

we know that

the standard form of quadratic polynomial is

x²-(alpha+beeta)x + alpha×beeta

x² - 2x +1
