3x^{2}\times \frac{1}{4}=108
x^{2} hosil qilish uchun x va x ni ko'paytirish.
\frac{3}{4}x^{2}=108
\frac{3}{4} hosil qilish uchun 3 va \frac{1}{4} ni ko'paytirish.
x^{2}=108\times \frac{4}{3}
Ikki tarafini \frac{4}{3} va teskari kasri \frac{3}{4} ga ko‘paytiring.
x^{2}=\frac{108\times 4}{3}
108\times \frac{4}{3} ni yagona kasrga aylantiring.
x^{2}=\frac{432}{3}
432 hosil qilish uchun 108 va 4 ni ko'paytirish.
x^{2}=144

Tenglamaning ikkala tarafining kvadrat ildizini chiqarish.
3x^{2}\times \frac{1}{4}=108
x^{2} hosil qilish uchun x va x ni ko'paytirish.
\frac{3}{4}x^{2}=108
\frac{3}{4} hosil qilish uchun 3 va \frac{1}{4} ni ko'paytirish.
\frac{3}{4}x^{2}-108=0
Ikkala tarafdan 108 ni ayirish.
x=\frac{0±\sqrt{0^{2}-4\times \frac{3}{4}\left(-108\right)}}{2\times \frac{3}{4}}
Ushbu tenglama standart shaklidadir: ax^{2}+bx+c=0. Kvadrat tenglama formulasida, \frac{-b±\sqrt{b^{2}-4ac}}{2a} \frac{3}{4} ni a, 0 ni b va -108 ni c bilan almashtiring.
x=\frac{0±\sqrt{-4\times \frac{3}{4}\left(-108\right)}}{2\times \frac{3}{4}}
0 kvadratini chiqarish.
x=\frac{0±\sqrt{-3\left(-108\right)}}{2\times \frac{3}{4}}
-4 ni \frac{3}{4} marotabaga ko'paytirish.
x=\frac{0±\sqrt{324}}{2\times \frac{3}{4}}
-3 ni -108 marotabaga ko'paytirish.
x=\frac{0±18}{2\times \frac{3}{4}}
324 ning kvadrat ildizini chiqarish.
x=\frac{0±18}{\frac{3}{2}}
2 ni \frac{3}{4} marotabaga ko'paytirish.
x=12
x=\frac{0±18}{\frac{3}{2}} tenglamasini yeching, bunda ± musbat. 18 ni \frac{3}{2} ga bo'lish 18 ga k'paytirish \frac{3}{2} ga qaytarish.
x=-12
x=\frac{0±18}{\frac{3}{2}} tenglamasini yeching, bunda ± manfiy. -18 ni \frac{3}{2} ga bo'lish -18 ga k'paytirish \frac{3}{2} ga qaytarish.
x=12 x=-12
Tenglama yechildi.
