Question

Hey ❤️❤️❤️❤️❤️❤️
Pls Answer this✔️​✔️

m,n are zeros of
$a {x}^{2} - 12x + c$
Find Value of a and c if
$m + n = mn = 3$

​

Answer 1

From question,

m+n = -b/a= 12/a

m+n = 12/a = 3 ( given in question that m+n = mn = 3)

a = 4

mn = c/a = c/4 ( we found a=4)

mn = c/4 = 3 ( given in question that m+n=mn=3)

c = 12

So, a= 4, c=12

Hope you have understood.
