Answer: which is the same as
If the math notation does not load properly, or the font size is too small, then it says ( (x+4)(x-1) )/( (x+4)(x+2) ) which is the same as (x^2+3x-4)/(x^2+6x+8)
==========================================================
Explanation:
We see that x cannot equal -2, as this prevents the denominator (x+2) from becoming zero. If x = -4, then x+4 = 0. So x not allowed to be -4 means (x+4) is prevented in being zero, and this is the missing factor in the denominator. We can never divide by zero.
Multiply top and bottom of this given fraction by (x+4) to get
Note how the (x+4) terms divide and cancel to get back to the original fraction given. The portion sticks around to make sure the domains line up properly.
----------
Optionally you can expand out each product in the numerator and denominator to get
(x+4)(x-1) = x^2-x+4x-4 = x^2+3x-4
(x+4)(x+2) = x^2+2x+4x+8 = x^2+6x+8
I used the FOIL rule
So,
Answer:
4x - 3 = 25
+ 3 + 3
4x = 28
x = 7
<em>1st = add like terms</em>
<em>2nd = simplify</em>
<em>3rd = divide both sides</em>

Answer:
y + 2 = 3(x - 1).
Step-by-step explanation:
Using the point-slope form of a line:
y - y1 = m(x - x1)
Here m = 3 and (x1, y1) = (1, -2) so we have the equation:
y - (-2) = 3(x - 1)
y + 2 = 3(x - 1).
