-77=n-4(3-3n)n=

Solution for -77=n-4(3-3n)n= equation:

-77=n-4(3-3n)n=

We move all terms to the left:

-77-(n-4(3-3n)n)=0

We add all the numbers together, and all the variables

-(n-4(-3n+3)n)-77=0


We calculate terms in parentheses: -(n-4(-3n+3)n), so:

n-4(-3n+3)n

We multiply parentheses

12n^2+n-12n

We add all the numbers together, and all the variables

12n^2-11n

Back to the equation:

-(12n^2-11n)


We get rid of parentheses

-12n^2+11n-77=0

a = -12; b = 11; c = -77;
Δ = b2-4ac
Δ = 112-4·(-12)·(-77)
Δ = -3575
Delta is less than zero, so there is no solution for the equation
