0=x^2+5x+10
We move all terms to the left:
0-(x^2+5x+10)=0
We add all the numbers together, and all the variables
-(x^2+5x+10)=0
We get rid of parentheses
-x^2-5x-10=0
We add all the numbers together, and all the variables
-1x^2-5x-10=0
a = -1; b = -5; c = -10;
Δ = b2-4ac
Δ = -52-4·(-1)·(-10)
Δ = -15
Delta is less than zero, so there is no solution for the equation
