Please help me out and explain it to me

A

Step-by-step explanation:

x^2-6x+25=0

A quadratic equation can be solved by using the quadratic formula,

So the equation to start with is ax^2+bx+c=0, thus your equation has the same layout.

a= 1

b= -6

c= 25

Then plug it in

When you have a negative in the root you have to take out an i

i = -

So when you take it out the negative isn't there anymore so you can simplify normally

Now split up the plus and minus

So the answer is A
