Baham ko'rish
Klipbordga nusxa olish
\frac{112\left(a+1\right)^{2}}{112}=\frac{3405}{112}
Ikki tarafini 112 ga bo‘ling.
\left(a+1\right)^{2}=\frac{3405}{112}
112 ga bo'lish 112 ga ko'paytirishni bekor qiladi.
a+1=\frac{\sqrt{23835}}{28} a+1=-\frac{\sqrt{23835}}{28}
Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.
a+1-1=\frac{\sqrt{23835}}{28}-1 a+1-1=-\frac{\sqrt{23835}}{28}-1
Tenglamaning ikkala tarafidan 1 ni ayirish.
a=\frac{\sqrt{23835}}{28}-1 a=-\frac{\sqrt{23835}}{28}-1
O‘zidan 1 ayirilsa 0 qoladi.
