Question

If a, ß are zeroes of the quadratic polynomial ply)
B
3y2-6y+4, find the value of
+3aß .
​

Answer 1

Step-by-step explanation:

3y2 - 6y + 4

alpha + beta = -b/a

alpha × beta = c/a

alpha + beta = 2

alpha × beta = 4/3

so value of 3 alpha × beta is

= 3 × 4/3

= 4

hence value of 3 alpha × beta is 4
