(2.2x^2)(5x)=16x^2
We move all terms to the left:
(2.2x^2)(5x)-(16x^2)=0
determiningTheFunctionDomain -16x^2+(2.2x^2)5x=0
We multiply parentheses
-16x^2+10x^2=0
We add all the numbers together, and all the variables
-6x^2=0
a = -6; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-6)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
