Answer:
none of these are right but the answer is 2x - y = -1.
D would be right but there is a negative sign in front of 2x.
Step-by-step explanation:
1
Move everything to the left by subtracting 25 from both sides:
Both terms are squares: 
is the square of 
, while 25 is the square of 5. So, we can apply the factoring
To factor the expression as
A multiplication is zero if and only if one of the factors is zero, so we have
2
The discriminant of the quadratic expression 
is defined as
So, you have
3
Similarly, we have
