Kvadrat tenglamalaridan foydalanish qoidalari

8m^{2} ni olish uchun 2m^{2} va 6m^{2} ni birlashtirish.

$$8m^{2}=1$$

Ikkala tarafdan 1 ni ayirish.

$$8m^{2}-1=0$$

Ushbu tenglama standart shaklidadir: ax^{2}+bx+c=0. Kvadrat tenglama formulasida, \frac{-b±\sqrt{b^{2}-4ac}}{2a} 8 ni a, 0 ni b va -1 ni c bilan almashtiring.

$$m=\frac{0±\sqrt{0^{2}-4\times 8\left(-1\right)}}{2\times 8}$$

0 kvadratini chiqarish.

$$m=\frac{0±\sqrt{-4\times 8\left(-1\right)}}{2\times 8}$$

-4 ni 8 marotabaga ko'paytirish.

$$m=\frac{0±\sqrt{-32\left(-1\right)}}{2\times 8}$$

-32 ni -1 marotabaga ko'paytirish.

$$m=\frac{0±\sqrt{32}}{2\times 8}$$

32 ning kvadrat ildizini chiqarish.

$$m=\frac{0±4\sqrt{2}}{2\times 8}$$

2 ni 8 marotabaga ko'paytirish.

$$m=\frac{0±4\sqrt{2}}{16}$$
