Which model shows the correct factorization of x2 – x – 2?
2 answers:
Answer: The correct factors are
(x-1) and (x+2)
Step-by-step explanation:
Step one :
To factorize the equation
x²– x – 2=0
First we look for numbers that when multiplied will result to the constant term and when added will result to the second term (1x, - 2x)
Step two :
We replace the second term with these factors we have
x²–(x-2x)–2=0
x²–x+2x–2=0
Factoring the expression we have
x(x–1)+2(x–1)=0
Hence the factors will be
(x-1) and (x+2)
Answer:
Model Number 2

Um well lets see there is no question so the day that ends in y
F = 41
E = 90
D = 49
from D to E is 55
then E to F also known as X = 36.08 or 41.51
