x=(2/5)(8*9)
We move all terms to the left:
x-((2/5)(8*9))=0
We add all the numbers together, and all the variables
x-((+2/5)72)=0
We multiply all the terms by the denominator
x*5)72)-((+2=0
Wy multiply elements
5x^2+2=0
a = 5; b = 0; c = +2;
Δ = b2-4ac
Δ = 02-4·5·2
Δ = -40
Delta is less than zero, so there is no solution for the equation
