5x/2=21+(2/30
We move all terms to the left:
5x/2-(21+(2/30)=0
We add all the numbers together, and all the variables
5x/2-(21+(+2/30)=0
We calculate fractions
150x^2/()+()/()=0
We add all the numbers together, and all the variables
150x^2/()+1=0
We multiply all the terms by the denominator
150x^2+1*()=0
We add all the numbers together, and all the variables
150x^2=0
a = 150; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·150·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
