We calculate fractions
(-5x^2)/()+()/()=0
We add all the numbers together, and all the variables
(-5x^2)/()+1=0
We multiply all the terms by the denominator
(-5x^2)+1*()=0
We add all the numbers together, and all the variables
(-5x^2)=0
We get rid of parentheses
-5x^2=0
a = -5; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-5)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
