We have that
<span>10x - 4 = 2 ( ? )
</span>I proceed to replace the missing value with the given expression
case a-------------> <span>5x - 4
</span><span>then
</span>10x - 4 = 2 (5x-4 )--------> 10x - 4 = 10x-8--------> is not solution
case b-------------> 5x - 2
then
10x - 4 = 2 (5x-2 )--------> 10x - 4 = 10x-4--------> is solution
case c-------------> <span>10x - 4
</span>then
10x - 4 = 2 (10x - 4 )--------> 10x - 4 = 20x-8--------> is not solution
case d-------------> <span>10x - 8
</span>then
10x - 4 = 2 (10x - 8 )--------> 10x - 4 = 20x-16--------> is not solution
the answer is the option b) 5x - 2
To have 2 real number solutions the discriminant b^2 - 4ac must be greater than zero.
so the condition for 2 real roots in this equation is:-
b^2 - 4*1*5 > 0
b^2 > 20
b > sqrt 20 ( positive root) Answer
The answer would be 6:15 since it can be divided by two and equal 3:5, i think
