Hey there !
x²-10x+25
=x²-5x-5x+25
=x(x-5)-5(x-5)
=(x-5)(x-5)
=(x-5)²
hope helped !

Given= x²-10x+25=0.
(if there is no = sign then it is not a equation)
Step 1- Middle term splitting
In this we have to spilt the middle term (here, -10x) in such a way that there sum is equal to the original one and its multiplication is equal to the product of remaining two terms
x²-5x-5x+25=0
here,(-5x)+(-5x)=-10 x (original term)
Step 2= Pairing
x(x-5)-5(x-5)=0
Step 3= Finding common and grouping
(x-5)(x-5)=0
