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:
the sun may rise or will not rise , so there are 2 chances
Step-by-step explanation:
so the probability is 1/2=0.5
Hey!
So It would be set up as .75n -2 = 10
.75 is the same as 3/4
Now add 2 to both sides
.75n = 12
now we want to get n alone so that we know what the number is, so divide .75 to both sides since it's multiplied to n
n=16
The answer is D!
Hope this helps!

Pls mark brainliest
80 * 1/4 = 80 /4 = 20
80-20= 60
