0=0013x^2+6.63x+6429
We move all terms to the left:
0-(0013x^2+6.63x+6429)=0
We add all the numbers together, and all the variables
-(0013x^2+6.63x+6429)=0
We get rid of parentheses
-0013x^2-6.63x-6429=0
We add all the numbers together, and all the variables
-13x^2-6.63x-6429=0
a = -13; b = -6.63; c = -6429;
Δ = b2-4ac
Δ = -6.632-4·(-13)·(-6429)
Δ = -334264.0431
Delta is less than zero, so there is no solution for the equation
