Hello,Originally Posted byDenMac21

the bad news first: The right solution is:

The first root is defined for

the second root is defined for

that means the LHS of your inequality is defined for

For all x from 0 to 4 the first root is greater than 3, that means the inequality is true for

For all x greater than 4 the second root alone has a value greater than

Therefore the inequality is true for all
