7mm=7m eching

$$7 m m = 7 m$$

m uchun yechish

$$m=1$$

$$m=0$$

Faktorlash qadamlari

7ni ikki tarafidan bekor qilish.

$$mm=m$$

m^{2} hosil qilish uchun m va m ni ko'paytirish.

$$m^{2}=m$$

Ikkala tarafdan m ni ayirish.

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

m omili.

$$m\left(m-1\right)=0$$

Tenglamani yechish uchun m=0 va m-1=0 ni yeching.

$$m=0 m=1$$

Kvadrat tenglamalaridan foydalanish qoidalari

7ni ikki tarafidan bekor qilish.

$$mm=m$$

m^{2} hosil qilish uchun m va m ni ko'paytirish.

$$m^{2}=m$$

Ikkala tarafdan m ni ayirish.

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

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

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

1 ning kvadrat ildizini chiqarish.

$$m=\frac{-\left(-1\right)±1}{2}$$

-1 ning teskarisi 1 ga teng.

$$m=\frac{1±1}{2}$$

m=\frac{1±1}{2} tenglamasini yeching, bunda ± musbat. 1 ni 1 ga qo'shish.

$$m=\frac{2}{2}$$

2 ni 2 ga bo'lish.

$$m=1$$

m=\frac{1±1}{2} tenglamasini yeching, bunda ± manfiy. 1 dan 1 ni ayirish.

$$m=\frac{0}{2}$$

0 ni 2 ga bo'lish.

$$m=0$$

Tenglama yechildi.

$$m=1 m=0$$

Kvadratni yakunlash bo'yicha qadamlar

7ni ikki tarafidan bekor qilish.

$$mm=m$$

m^{2} hosil qilish uchun m va m ni ko'paytirish.

$$m^{2}=m$$

Ikkala tarafdan m ni ayirish.

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

-1 ni bo‘lish, x shartining koeffitsienti, 2 ga -\frac{1}{2} olish uchun. Keyin, -\frac{1}{2} ning kvadratini tenglamaning ikkala tarafiga qo‘shing. Ushbu qadam tenglamaning chap qismini mukammal kvadrat sifatida hosil qiladi.

$$m^{2}-m+\left(-\frac{1}{2}\right)^{2}=\left(-\frac{1}{2}\right)^{2}$$

Kasrning ham suratini, ham maxrajini kvadratga ko'paytirib -\frac{1}{2} kvadratini chiqarish.

$$m^{2}-m+\frac{1}{4}=\frac{1}{4}$$

m^{2}-m+\frac{1}{4} omili. Odatda, x^{2}+bx+c mukammal kvadrat bo'lsa, u doimo \left(x+\frac{b}{2}\right)^{2} omil sifatida bo'lishi mumkin.

$$\left(m-\frac{1}{2}\right)^{2}=\frac{1}{4}$$

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

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

Qisqartirish.

$$m-\frac{1}{2}=\frac{1}{2} m-\frac{1}{2}=-\frac{1}{2}$$

\frac{1}{2} ni tenglamaning ikkala tarafiga qo'shish.

$$m=1 m=0$$
