You can write this as
Squaring both sides, , . By the "rational root theorem" the only possible rational roots are x= 1, x= -1, x= 2, x= -2, x= 4, and x= -4. Try those to see if any are actually roots.
Almost trivial: . Assuming that "log" here means common logarithm, . Solve that quadratic equation.[*]
Similar to the first one isn't it? means so and .[*]
Yes, that is correct.And for this problem, can you check if I solved it right:
