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:

(d) none of the above.

Step-by-step explanation:

Sum of zeroes=-3+4=1=-b/a

Product of zeroes=-3×4=-12=c/a

Here, a=1, b=-1 and c=-12

Comparing the given polynomial with ax²+bx+c we get

x²-x-12

Therefore, option (d) is correct.
