Factor it out first so:
y=(x+13)(x-2)
Then you know that x= -13 and 2 to make the equation 0
Hope this helps!

Answer:
2sqrt3
Step-by-step explanation:
Since this seems to be a 45, 45, 90 triangle, x and y are the same.
The hypoteneuse is always the side lengths *sqrt2
We divide the hypoteneuse by sqrt 2 and get sqrt12
sqrt12 simplified is 2sqrt3

Answer:</h3>
- slope = 1/2
- equation: y = 1/2x +5
<h3>
Step-by-step explanation:</h3>
Slope
The slope of the line between two points (x1, y1) and (x2, y2) is ...
... m = (y2 -y1)/(x2 -x1)
For your given points, the slope is
... m = (4 -9)/(-2 -8) = -5/-10
... m = 1/2
Equation
The point-slope form of the equation for a line can be written ...
... y = m(x -h) +k . . . . for a line of slope m through point (h, k)
Using the first point given and the slope just calculated, the equation for the line can be written ...
... y = (1/2)(x -8) +9
... y = (1/2)x -4 +9 . . . . eliminate parentheses; next, collect terms
... y = 1/2x +5
answer
Step-by-step explanation:
equation: 3x(x + 4) + 3(x + 4) = 0
distribute 3x into your (x+4)
that'll give you : 
now distribute your 3 into your (x+4)
that'll give you 
now combine like terms and you'll end up with
hope this helps
