Question

What is 1+1 and what x2+25-10x

Answer 1

hi mate,

1 + 1 = 2

and

Factoring x²-10x+25

x² - 5x - 5x - 25

Step1: Add up the first 2 terms, pulling out like factors :

x • (x-5)

Add up the last 2 terms, pulling out common factors :

5 • (x-5)

Step2: Add up the four terms of step1 :

(x-5) • (x-5)

Which is the desired factorization

Final result : (x - 5)²

i hope it helps you.
