$$1111\Delta t-49\Delta t^{2}=-3634$$

ຮວມທຸກຄຳສັບທີ່ມີ \Delta .

$$\left(1111t-49t^{2}\right)\Delta =-3634$$

ຫານທັງສອງຂ້າງດ້ວຍ 1111t-49t^{2}.

$$\frac{\left(1111t-49t^{2}\right)\Delta }{1111t-49t^{2}}=-\frac{3634}{1111t-49t^{2}}$$

ການຫານດ້ວຍ 1111t-49t^{2} ຈະຍົກເລີກການຄູນດ້ວຍ 1111t-49t^{2}.

$$\Delta =-\frac{3634}{1111t-49t^{2}}$$

ຫານ -3634 ດ້ວຍ 1111t-49t^{2}.

$$\Delta =-\frac{3634}{t\left(1111-49t\right)}$$

ແກ້ສຳລັບ t (complex solution)

$$t=\frac{\sqrt{1234321\Delta ^{2}+712264\Delta }}{98\Delta }+\frac{1111}{98}$$

$$t=-\frac{\sqrt{1234321\Delta ^{2}+712264\Delta }}{98\Delta }+\frac{1111}{98}\text{, }\Delta \neq 0$$

ແກ້ສຳລັບ t

$$t=\frac{\sqrt{1234321\Delta ^{2}+712264\Delta }}{98\Delta }+\frac{1111}{98}$$

$$t=-\frac{\sqrt{1234321\Delta ^{2}+712264\Delta }}{98\Delta }+\frac{1111}{98}\text{, }\Delta >0\text{ or }\Delta \leq -\frac{712264}{1234321}$$
