3^x*9^x+2=1/27
We move all terms to the left:
3^x*9^x+2-(1/27)=0
We add all the numbers together, and all the variables
3^x*9^x+2-(+1/27)=0
Wy multiply elements
27x^2+2-(+1/27)=0
We get rid of parentheses
27x^2+2-1/27=0
We multiply all the terms by the denominator
27x^2*27-1+2*27=0
We add all the numbers together, and all the variables
27x^2*27+53=0
Wy multiply elements
729x^2+53=0
a = 729; b = 0; c = +53;
Δ = b2-4ac
Δ = 02-4·729·53
Δ = -154548
Delta is less than zero, so there is no solution for the equation
