Answer:
plsarked me as a brainlist
firstly we take sq root of 100 that is 10².
then,
(10)²-(x–5)²
=5(10+x–5) 5(10–x+5)
=(5+x)(5–x)

Given:
100-(x-5)²
To find:
Factorized form of 100-(x-5)²
Solution:
The factorized form of 100-(x-5)² is (15-x)(5-x).
We can find the factors by following the steps given below-
We know that the given expression can be factorized by using the following formula-
a²-b²=(a-b)(a+b)
The given expression= 100-(x-5)²
It can also be written as 10²-(x-5)²
Using the aforementioned formula,
10²-(x-5)²=(10-(x-5)(10+(x-5))
On solving it, we get
=(10-x-(-5))(10+x-5)
=(10-x+5)(10-x-5)
=(15-x)(5-x)
On factorizing 100-(x-5)², we get (15-x)(5-x).
Therefore, the factorized form of 100-(x-5)² is (15-x)(5-x).
