Answer:
(x -y -1)(x +y)
Step-by-step explanation:
The expression can be factored by grouping.
x^2 -y^2 -x -y = (x^2 -y^2) -(x +y)
= (x -y)(x +y) -1(x +y)
= (x -y -1)(x +y)
_____
It is useful to know that a difference of squares is factored as ...
a^2 -b^2 = (a -b)(a +b)
4y^3 - 2y^2
what is the largest number that divides evenly into 4y^3 and -2y^2?
it is 2
what is the highest degree of y that divides evenly into 4y^3 and -2y^2
it is y^2
the GCF is 2y^2
2y^2(2y - 1) <<<< answer
hope that helps, God bless!
Answer:
None of those answers are right. It should be
Step-by-step explanation:
You have to find common denominators first. Multiply -5/6 by 4/4 to get -20/24. Multiply 1/8 by 3/3 to get 3/24.
Subtract 3/24 from both sides since it is being added.
Since there are two negatives on the left, add the fractions together and keep the negative sign.
You cannot reduce this fraction.
