Question

Choose the pair(s) of integers that can be substituted into the equation ax2 - 6x + c = 0 so that it has two real solutions.

Answer 1

The options are not provided, but method is stated below

Answer:

Quadratic equation ax2 - 6x + c = 0

options would be given for a and c

1. substitute a and c
2. check for Discriminant
3.  $b^2 - 4ac \geq 0$
4. 36 -4ac $\geq 0$

These conditions will fetch us the result required among the options.

Note : the $\geq$ sign will give us the result for Two real unequal solutions and two real equal solutions.  If we only need Real unequal solutions we only use > sign instead of $\geq$
