Step-by-step explanation:

Given

x² - 9x + 20 = 0

x² - ( 4 + 5) x + 20 = 0

x² - 4x - 5x + 20 = 0

x ( x - 4 ) - 5 (x - 4 ) = 0

(x - 4 ) ( x - 5 ) = 0

Either

x - 4 =0

x = 4

x - 5 =0

x = 5

x = 4 and 5

Hope it will help :)

It is not having a definite property it is a way commonly used with algebraic expressions
26 = 8 + x (here, we put x instead of the number we don't know)
you can take 8 to the other side with 26 but it will be minus instead of plus
26 - 8 = ×
18 = x
