x uchun yechish (complex solution)

$$\left\{\begin{matrix}\\x=0\text{, }&\text{unconditionally}\\x\in \mathrm{C}\text{, }&x_{3}=0\end{matrix}\right,$$

Kvadrat ildizini topish bo'yicha qadamlar

7x_{3} ga bo'lish 7x_{3} ga ko'paytirishni bekor qiladi.

$$x^{2}=\frac{0}{7x_{3}}$$

0 ni 7x_{3} ga bo'lish.

$$x^{2}=0$$

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$x=0 x=0$$

Tenglama yechildi. Yechimlar bir xil.

$$x=0$$

Kvadrat tenglamalaridan foydalanish qoidalari

Bu kabi kvadrat tenglamalarni x^{2} sharti bilan, biroq x shartisiz hamon kvadrat tenglamasidan foydalanib yechish mumkin, \frac{-b±\sqrt{b^{2}-4ac}}{2a}, ular standart formulaga solingandan so'ng: ax^{2}+bx+c=0.

$$7x_{3}x^{2}=0$$

Ushbu tenglama standart shaklidadir: ax^{2}+bx+c=0. Kvadrat tenglama formulasida, \frac{-b±\sqrt{b^{2}-4ac}}{2a} 7x_{3} ni a, 0 ni b va 0 ni c bilan almashtiring.

$$x=\frac{0±\sqrt{0^{2}}}{2\times 7x_{3}}$$

0^{2} ning kvadrat ildizini chiqarish.

$$x=\frac{0±0}{2\times 7x_{3}}$$

2 ni 7x_{3} marotabaga ko'paytirish.

$$x=\frac{0}{14x_{3}}$$

0 ni 14x_{3} ga bo'lish.

$$x=0$$
