When u add it stays the same but for subtraction u change the sign.
Example: 2- (-5)=7
Answer:
-2
Step-by-step explanation:
In slope intercept form equations, y = 0.5x - 2 for example,
0.5 would be m or the slope, and the number after the x - 2 would
be your y-intercept
Answer:
no
Step-by-step explanation:
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)
