Respuesta :

Answer:

B

Step-by-step explanation:

u find two numbers that multiply and equal 100 such as -10 ,and -10 that when added up equal the second term -20 and since x has nothing next to it u get (x-10) but you square it because both term answers are the same so you end up with

(x-10)squared
