Question

to fight corona a team exist of 8 doctors and 12 nurses write a quadratic polynomial whose roots are equal to number of doctors and number of nurses respectively ​

Answer 1

Answer:

x²-20x+96

Step-by-step explanation:

a= alpha

b= beta

a=8, b= 12

(alpha plus beta)

a+b= 8+12

a+b= 20

(alpha beta)

a*b= 8×12 = 96

( x² minus alpha plus beta*x plus alpha beta)

x²-(a+b)x + (ab)

x²-20x + 96

I hope it was understandable :)
