(-4)=1x^2+3x+4
We move all terms to the left:
(-4)-(1x^2+3x+4)=0
We add all the numbers together, and all the variables
-(1x^2+3x+4)-4=0
We get rid of parentheses
-1x^2-3x-4-4=0
We add all the numbers together, and all the variables
-1x^2-3x-8=0
a = -1; b = -3; c = -8;
Δ = b2-4ac
Δ = -32-4·(-1)·(-8)
Δ = -23
Delta is less than zero, so there is no solution for the equation
