Question

14. Find the quadratic polynomial, the sum and product of whose zeroes are -2√3 and -9. Also

find its zeroes.​

Answer 1

Step-by-step explanation:

x2 + 2_/3x -9 =0 is your answer.

this is the general format to solve these type of questions :-

x^2 - (sum of roots)x + (product of roots) = 0

here sum of roots = -2_/3

and product of roots = -9

can you mark me brainliest as I only need 1 plss plss plss I got 4/5 to reach the next rank

thank you sooo sooo muchh

Answer 2

Answer:

a²+2√3a-9

Step-by-step explanation:

let the roots of quadratic equation x,y.

by given data,

x+y= -2√3

xy= -9

the Q.E equation having roots x,y is

a²-(x+y)a+ab

a²+2√3a-9
