\left(x+1\right)\left(\frac{2\left(x+1\right)}{x\left(x+1\right)}+\frac{x}{x\left(x+1\right)}\right)

ເພື່ອເພີ່ມ ຫຼື ຫານນິພົດ, ໃຫ້ຂະຫຍາຍພວກມັນເພື່ອໃຫ້ຕົວຄູນມີຈຳນວນດຽວກັນ. ຈຳນວນຄູນທີ່ນິຍົມໜ້ອຍທີ່ສຸດຂອງ x ກັບ x+1 ແມ່ນ x\left(x+1\right). ຄູນ \frac{2}{x} ໃຫ້ກັບ \frac{x+1}{x+1}. ຄູນ \frac{1}{x+1} ໃຫ້ກັບ \frac{x}{x}.

\left(x+1\right)\times \frac{2\left(x+1\right)+x}{x\left(x+1\right)}

ເນື່ອງຈາກ \frac{2\left(x+1\right)}{x\left(x+1\right)} ແລະ \frac{x}{x\left(x+1\right)} ມີຕົວຫານດຽວກັນ, ໃຫ້ເພີ່ມພວກມັນໂດຍການເພີ່ມຈຳນວນທີ່ເປັນເສດໃນເລກເສດສ່ວນຂອງພວກມັນ.

\left(x+1\right)\times \frac{2x+2+x}{x\left(x+1\right)}

ຄູນໃນເສດສ່ວນ 2\left(x+1\right)+x.

\left(x+1\right)\times \frac{3x+2}{x\left(x+1\right)}

ຮວມຂໍ້ກຳນົດໃນ 2x+2+x.

\frac{\left(x+1\right)\left(3x+2\right)}{x\left(x+1\right)}

ສະແດງ \left(x+1\right)\times \frac{3x+2}{x\left(x+1\right)} ເປັນໜຶ່ງເສດສ່ວນ.

\frac{3x+2}{x}

ຍົກເລີກ x+1 ທັງໃນຕົວເສດ ແລະ ຕົວຫານ.

\left(x+1\right)\left(\frac{2\left(x+1\right)}{x\left(x+1\right)}+\frac{x}{x\left(x+1\right)}\right)

\left(x+1\right)\times \frac{2\left(x+1\right)+x}{x\left(x+1\right)}

\left(x+1\right)\times \frac{2x+2+x}{x\left(x+1\right)}

ຄູນໃນເສດສ່ວນ 2\left(x+1\right)+x.
