Question

write the quadratic polynomial whose zeros are 2, -1​

Answer 1

Answer:

sum of zeroes is=1 (b)

product of zeroes=-2(c)

p(x)=ax²+bx+c

p(x)=x²+x-2

Answer 2

➡️.... zeros ;- 2 and -1

let , quadratic polynomial be ;- ax2 + bx + c

Sum of zeros :- -b/a

2/1 = -b/a

so , here

b = -2

a = 1

product of zero :- c/a

-1/1 = c/a

c= -1

a = 1

equation :- ax2 -2x -x
