Question

A quadratic polynomial whose zeroes are –3 and 4 is

(a) x2

– x +12 (b) x2

+x + 12 (c) 2x2

+ 2x – 24. (d) none of the above.​

Answer 1

Answer:

Polynomial whose roots are -3 and 4 can be written as a(x+3) (x-4)

So the polynomial become

a(x²-x-12) where a can be any constant

By this we can say none of the three option are correct.

So answer is D

Answer 2

Answer:

d)none of the above

Step-by-step explanation:

α=-3,ß=4

quadratic polynomial=k[x^2-(α+ß)x+αß]

=k[x^2-(-3+4)x+(-3)(4)]

=k[x^2-(1)x-12]

=k[x^2-1x-12)

if k=1->x^2-x+12
