Find the product of (x − 5)2

Igoryamba

Answer: The product is $x^2-10x+25$

Step-by-step explanation:

Since we have given that

$(x-5)^2$

We need to find the product:

Since we know that

$(a-b)^2=a^2-2ab+b^2$

Here, a = x

and

b = 5

So, it becomes,

$(x-5)^2=x^2-2\times x\times 5+5^2=x^2-10x+25$

Hence, the product is $x^2-10x+25$
