If the sum of the zeroes is sin 90° and product of the zeroes is 2 cosoº then
find the quadratic polynomial.​

Answer 1

Answer:

K(x^2-3x+2). where K is natural number

Step-by-step explanation:

let zeroes are a and b

then

a=sin90°=1

b=2cos0°=2

now quadratic should be

= Ax^2+Bx+C

where

a+b = -B/A

1+2. = -B/A

and

ab = C/A

1×2= C/A

so if A= 1 then B= -3 and C= 2

Hence quadratic is

=x^2-3x+2
