Yechim qadamlari

-21 hosil qilish uchun -3 va 7 ni ko'paytirish.

$$\left(-x^{2}\right)y-\left(-21x^{2}y\right)+\frac{16x^{2}y^{3}z}{4y^{2}z}$$

-21x^{2}y ning teskarisi 21x^{2}y ga teng.

$$\left(-x^{2}\right)y+21x^{2}y+\frac{16x^{2}y^{3}z}{4y^{2}z}$$

Surat va maxrajdagi ikkala 4zy^{2} ni qisqartiring.

$$\left(-x^{2}\right)y+21x^{2}y+4yx^{2}$$

25x^{2}y ni olish uchun 21x^{2}y va 4yx^{2} ni birlashtirish.

$$\left(-x^{2}\right)y+25x^{2}y$$

24x^{2}y ni olish uchun -x^{2}y va 25x^{2}y ni birlashtirish.

$$24x^{2}y$$

x ga nisbatan hosilani topish
