#:.k=5,-6#

Explanation:

Move all the unknowns to one side.

#3k^2+k-2k^2=30#
#k^2+k=30#
From this, we can see that by moving #30# to the left hand side, we can form a quadratic equation and solve for #k#.
#k^2+k-30=0#

You can use the quadratic formula to solve for #k# or use a calculator to find the values.

#:.k=5,-6#
