3/ x -1 - 4 / x + 2=2
I work a bit backwards so, lets try looking at it like this,
3/ X
-4/X
what could X be to let these be positive since our outcome is positive?
3/0=0
4/0=0
so 3/0-1= -1
-1-4/0= 0
+2= 2
so 2=2
so now we go and fill it in to make sure
3/0-1-4/0+2=2
and it works so,
X= 0
I hope this helped some
X^2 + 6x + 9
x 3
x 3
(x+3) (x+3)
x^2 + 3x + 3x + 9 (FOIL method)
x^2 + 6x + 9 (true)
your answer is 9 as the constant
hope this helps
To find the X intercept, replace y with 0 and solve for x:
9x + 21(0) = 16
9x = 16
x = 16/9
To find the Y intercept, replace x with 0 and solve for y:
9(0) + 21y = 16
21y = 16
y = 16/21
X-intercept is 16/9
y intercept is 16/21
