Need help: write the expression in a complete factored form: x²-9x+xy-9y
Galina-37 [17]
Factor this by grouping.  Group the first two terms together and then the second 2 terms together.  The idea here is that, after grouping, what you can pull out in both groups is the same.  Like this:
( x^{2} -9x)+(xy-9y)
Now work on finding a common thing between the 2 groups:
x(x-9)+y(x-9)
See, what you have in common there now is the (x-9) that you can factor out:
(x-9)(x+y)
And that is factored completely.

-7x - 5(-3x + 6) = 58 solve for x
Furkat [3]

Answer:

X= 11

Step-by-step explanation:

That equation becomes -7x+15x-30 =58

And add them all up giving you 8x-30=58

Add 30 to both sides

8x=88

Divide 88 by 8 which gives you 11

Semmy [17]
<span> Simplifying
4x + 4y = 0

 Solving
4x + 4y = 0

 Solving for variable 'x'.
 Move all terms containing x to the left, all other terms to the right.

 Add '-4y' to each side of the equation.
4x + 4y + -4y = 0 + -4y

 Combine like terms:
4y + -4y = 0
4x + 0 = 0 + -4y
4x = 0 + -4y

 Remove the zero:
4x = -4y

 Divide each side by '4'.
x = -1y

 Simplifying
x = -1y</span>
