Question

find sum and product of roots of the quadratic equation x2-4_/3x +9=0

Answer 1

Hi ,

Compare x² - ( 4/3 )x + 9 = 0 with

ax² + bx + c = 0 ,

a = 1 ,

b = -4/3 ,

c = 9 ,

sum of the roots = - b/a

= - ( -4/3 )/1

= 4/3

product of the roots = c/a

= 9/1

= 9

I hope this helps you.

Answer 2

Hii friend,

X²-(4/3)X +9 = 0

This equation is in the form of AX²+BX+C. where,

A = 1 , B= -4/3 and C = 9

We know that,

Sum of zeros = -B/A => -(-4/3) = 4/3

And,

Product of zeros = C/A => 9/1

HOPE IT WILL HELP YOU... :-)
