okay, so i need to find:
A) for which values of x is x^2 + x + 1 >= (x-1)/(2x-1)
and another similar one
for which values of x is -3x^2 +4x > 1?
Hello,
for confirmation only I give you the solution of the first one:
#2.
. Now factor the LHS of the inequaltiy:
. You have a product of 2 factors which is positiv. That means both factors must have the same sign. The sign + means that the value is greater than zero, the sign - ...:
. Solve each inequality:
. Collect the results of inequalities which are connected by :
