Question

Choose the correct set of options regarding the quadratic equation ( 5 m + 9 ) 2 x 2 − ( 3 n + 4 ) x + 1 = 0 where m , n ∈ Z .

Answer 1

Answer:

Both roots will be real and distinct if m=n

Step-by-step explanation:

substitute 5m+9 = p

and 3n +4 = q

$b^{2}-4ac$ for the original equation will be,

$9n^{2} -24n-20m-20$, now substitute different values for m and n provided in the options to find the right answer
