5x^2/6-x^2=72
We move all terms to the left:
5x^2/6-x^2-(72)=0
We add all the numbers together, and all the variables
-1x^2+5x^2/6-72=0
We multiply all the terms by the denominator
5x^2-1x^2*6-72*6=0
We add all the numbers together, and all the variables
5x^2-1x^2*6-432=0
Wy multiply elements
5x^2-6x^2-432=0
We add all the numbers together, and all the variables
-1x^2-432=0
a = -1; b = 0; c = -432;
Δ = b2-4ac
Δ = 02-4·(-1)·(-432)
Δ = -1728
Delta is less than zero, so there is no solution for the equation
