=(-E)E
We move all terms to the left:
-((-E)E)=0
We add all the numbers together, and all the variables
-((-1E)E)=0
We calculate terms in parentheses: -((-1E)E), so:We get rid of parentheses
(-1E)E
We multiply parentheses
-1E^2
Back to the equation:
-(-1E^2)
1E^2=0
We add all the numbers together, and all the variables
E^2=0
a = 1; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·1·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
