We add all the numbers together, and all the variables
(+2x/5)-((+7/35))=0
We get rid of parentheses
2x/5-((+7/35))=0
We calculate fractions
70x^2/()+()/()=0
We add all the numbers together, and all the variables
70x^2/()+1=0
We multiply all the terms by the denominator
70x^2+1*()=0
We add all the numbers together, and all the variables
70x^2=0
a = 70; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·70·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
