m^2=1 eching

$$m ^ { 2 } = 1$$

m uchun yechish

$$m=1$$

$$m=-1$$

Kvadratlar farqidan foydalangan qadamlar

Ikkala tarafdan 1 ni ayirish.

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

Hisoblang: m^{2}-1. m^{2}-1 ni m^{2}-1^{2} sifatida qaytadan yozish. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).

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

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

$$m=1 m=-1$$

Kvadrat ildizini topish bo'yicha qadamlar

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.

$$m=1 m=-1$$

Kvadrat tenglamalaridan foydalanish qoidalari

Ikkala tarafdan 1 ni ayirish.

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

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

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

0 kvadratini chiqarish.

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

-4 ni -1 marotabaga ko'paytirish.

$$m=\frac{0±\sqrt{4}}{2}$$

4 ning kvadrat ildizini chiqarish.

$$m=\frac{0±2}{2}$$

m=\frac{0±2}{2} tenglamasini yeching, bunda ± musbat. 2 ni 2 ga bo'lish.

$$m=1$$

m=\frac{0±2}{2} tenglamasini yeching, bunda ± manfiy. -2 ni 2 ga bo'lish.

$$m=-1$$

Tenglama yechildi.

$$m=1 m=-1$$
