I assume that your first problem reads:
Multiply by denominator. The next steps depends on the sign of the denominator!
. that means
or
. So the solution is:
2nd problem:
Solve this equation: . You'll get:
Because this equation belongs to a quadratic funtion which open upward, the part of the function between the zeros is below the x-axis, that means it is smaller than zero. Therefore your solution is:
