6x(9x+5)-3x+4x=-408+x
We move all terms to the left:
6x(9x+5)-3x+4x-(-408+x)=0
We add all the numbers together, and all the variables
6x(9x+5)-3x+4x-(x-408)=0
We add all the numbers together, and all the variables
x+6x(9x+5)-(x-408)=0
We multiply parentheses
54x^2+x+30x-(x-408)=0
We get rid of parentheses
54x^2+x+30x-x+408=0
We add all the numbers together, and all the variables
54x^2+30x+408=0
a = 54; b = 30; c = +408;
Δ = b2-4ac
Δ = 302-4·54·408
Δ = -87228
Delta is less than zero, so there is no solution for the equation
