How do you solve #3x ^ { 2} + n - 44= 0#?
1 Answer
It is impossible to solve, so the best option is to isolate.
Explanation:
You can't solve this equation because there are two variables.
With more than one variable undefined, there can be an infinite amount of possibilities. E.g.:
#3x^2+n-44=0#
#3(2)^2+(32)-44=0#
#12+32-44=0#
Or we can sub in...
#3x^2+n-44=0#
#3(5)^2+(~31)-44=0#
#75-31-44=0#
As you can see, there is an unlimited amount of variables that we can have. Unless we restrict one of them to a set value, then it is impossible to solve. The only thing we can do is to isolate and solve for that.
However, solving implies we determine the exact value of a variable, in which we can't do that here.
If we were to isolate, it would be like this:
#3x^2+n-44=0#
#3x^2=44-n#
#x^2=(n-44)/3#
#x=((n-44)/3)^2#
And for
#3x^2+n-44=0#
#3x^2+n=44#
#n=44-3x^2#
Hope this helps :)
