F(x)=1/x+x+x^2 eching

$$F ( x ) = \frac { 1 } { x } + x + x ^ { 2 }$$

Baholash

$$x^{2}+x+\frac{1}{x}$$

Qisqa yechim qadamlari

Ifodalarni qo‘shish yoki ayirish uchun ularni yoyib, maxrajlarini bir xil qiling. x+x^{2} ni \frac{x}{x} marotabaga ko'paytirish.

$$\frac{1}{x}+\frac{\left(x+x^{2}\right)x}{x}$$

\frac{1}{x} va \frac{\left(x+x^{2}\right)x}{x} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{1+\left(x+x^{2}\right)x}{x}$$

1+\left(x+x^{2}\right)x ichidagi ko‘paytirishlarni bajaring.

$$\frac{1+x^{2}+x^{3}}{x}$$

Omil

$$\frac{x^{3}+x^{2}+1}{x}$$
