Which of the following equations is a quadratic equation? HELP ASAP

Answer:
(x+5)(x+25)=5
Step-by-step explanation:
When simplified, if you foil the left side of the equation, you get:
x^2+30x+125 = 5
Simplified, you get:
x^2+30x+120 = 0
A quadratic by definition is a polynomial with the highest degree of 2, which means the highest exponent should be a two. In our case, it is. So therefore, (x+5)(x+25)=5 is the answer.
Answer:
Option 1
Step-by-step explanation:
(x + 5)(x + 25) = 5 is a quadratic equation. It can be verified upon expansion.
=> x² + 30x + 125 = 0
=> Quadratic equations are of the form Ax² + Bx + C = 0
=> Hence it is a quadratic equation
