Question

If 3 and -3 are the solutions of mx²+nx-9=0 , then the values of m and n are.​

Answer 1

Step-by-step explanation:

If p and q are solutions of a quadratic equation

$a {x}^{2} + bx + c = 0$

p+q=-b/a

p.q=c/a

Applying the same concept:

3+ -3 = -n/m

0=-n/m

n=0

3×-3=-9/m

-9=-9/m

m=1
