\frac{4-p}{\left(p-6\right)\left(-p-6\right)}+\frac{p+3}{p-6}

ຕົວປະກອບ 36-p^{2}.

\frac{4-p}{\left(p-6\right)\left(-p-6\right)}+\frac{\left(p+3\right)\left(-p-6\right)}{\left(p-6\right)\left(-p-6\right)}

ເພື່ອເພີ່ມ ຫຼື ຫານນິພົດ, ໃຫ້ຂະຫຍາຍພວກມັນເພື່ອໃຫ້ຕົວຄູນມີຈຳນວນດຽວກັນ. ຈຳນວນຄູນທີ່ນິຍົມໜ້ອຍທີ່ສຸດຂອງ \left(p-6\right)\left(-p-6\right) ກັບ p-6 ແມ່ນ \left(p-6\right)\left(-p-6\right). ຄູນ \frac{p+3}{p-6} ໃຫ້ກັບ \frac{-p-6}{-p-6}.
