The teacher will be very surprised to see your correct solution 😉
_______________ 5 / / 2 \ \/ log\x - 4*x/ = 1
sum
_______ _______ 2 - \/ 4 + E + 2 + \/ 4 + E
=
4
product
/ _______\ / _______\ \2 - \/ 4 + E /*\2 + \/ 4 + E /
=
-E
-E
_______ x1 = 2 - \/ 4 + E
_______ x2 = 2 + \/ 4 + E
x2 = 2 + sqrt(E + 4)
