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
Answer:
its C
Step-by-step explanation:
its a positive number bc there is no - in the equation and x is the unknown number
The parent function was moved left one and down five. It also opened up due to the 1/2
