Learn How To Expand (X-5)² With Step-By-Step Formula | Math Tutorial

(x-5)²

x²-10x+25

To expand (x-5)², we can use the formula for square of a binomial, which is:

(a – b)² = a² – 2ab + b²

Using this formula with a = x and b = 5, we get:

(x – 5)² = x² – 2(x)(5) + 5²
= x² – 10x + 25

Therefore, the expanded form of (x-5)² is:

x² – 10x + 25.
