6n^2-18n=24
answer and thorough explanation

n1=1,n2=4

Step-by-step explanation:

first divide both sides by 6 of the equation

=n^2-3n=4

n^2-3n-4=0..move the constant to the outerside

n^2-3n-4=0...write -3 as a difference

n^2+n-4n-4=0

factor out n

n×(n+1)-(4n-4)=0

nx(n+1)-4(n+1)=0

(n+1)×(n-4)=0

=n(+1=0)work out

n-4=0

n=-1

n-4=0

now solve for n

and the answer will be ;n1=-1,n2=4

answer is c

step-by-step explanation:

its a straight line parallel to the time axis
