Factor because if we have
yz=0 then we can assume y and/or z=0
so factor
so the easiest way is to find what 2 numbers add to -6 and multiply to get 9 so
we know that they must be both - because we must have x+x=(-) and x^2=+ so therefor they must be negative
factors of 9=3 and 3 so
-3 and -3
-3+-3=-6 perfect
(z-3)(z-3)=0
set each to zero
z-3=0
add 3
z=3
z=3 is the answer
The equation in slope intercept form is
Y=.5x+3
The answer would be 4c^2+8c+3
The arrow stands for squared off you didn’t already know but these are very easy to solve because you just multiply it out
I hope this helps.....
Explanation:
I took this in 9th grade so I know how to do this kind of stuff
It is called the slope of the line
