$$p = \pm12$$
First you subtract 144 from both sides $$-p^2 = -144$$ Then you divide by -1 on both sides $$p^2 = 144$$ Then you find the square root of both sides $$p= \pm12$$ That is your final answer since the variable is alone now. Remember you always have to put the plus or minus sign ($\pm$) because any number under the square root that is above $0$ has $2$ has answers.
