8^x*16^x=4^72-x
We move all terms to the left:
8^x*16^x-(4^72-x)=0
Wy multiply elements
128x^2-(4^72-x)=0
We get rid of parentheses
128x^2+x-4^72=0
We add all the numbers together, and all the variables
128x^2+x+43-2.23007451985E=0
We add all the numbers together, and all the variables
128x^2+x+36.9380289566=0
a = 128; b = 1; c = +36.9380289566;
Δ = b2-4ac
Δ = 12-4·128·36.9380289566
Δ = -18911.2708258
Delta is less than zero, so there is no solution for the equation
