5d2-50d+125 =

Fully factor each expression

First, let's start off by simplifying as much as possible before factoring.

5d^2 - 50d + 125

We can divide all the numbers by 5 in order to simplify it:

5 (d^2 - 10d + 25)

Now all we need to do is factor.

Since - 5*-5 = 25 and - 5 - 5 = - 10, we can use this to factor:

5 (d - 5) (d - 5)

Or

5 (d - 5) ^2
