Yechim qadamlari

Avval noaniq integralni baholang.

$$\int 2x+2-1-2x^{2}-2x^{2}+x\mathrm{d}x$$

Summani muddatma-muddat integratsiya qiling.

$$\int 2x\mathrm{d}x+\int 2\mathrm{d}x+\int -1\mathrm{d}x+\int -2x^{2}\mathrm{d}x+\int -2x^{2}\mathrm{d}x+\int x\mathrm{d}x$$

Har bir shartda konstantani qavsdan tashqariga oling.

$$2\int x\mathrm{d}x+\int 2\mathrm{d}x+\int -1\mathrm{d}x-2\int x^{2}\mathrm{d}x-2\int x^{2}\mathrm{d}x+\int x\mathrm{d}x$$

k\neq -1 uchun integral \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} boʻlgani uchun, \int x\mathrm{d}x integralni \frac{x^{2}}{2} bilan almashtiring. 2 ni \frac{x^{2}}{2} marotabaga ko'paytirish.

$$x^{2}+\int 2\mathrm{d}x+\int -1\mathrm{d}x-2\int x^{2}\mathrm{d}x-2\int x^{2}\mathrm{d}x+\int x\mathrm{d}x$$

\int a\mathrm{d}x=ax umumiy integrallar qoidasi jadvalidan foydalanib, -1 integralini toping.

$$x^{2}+2x-x-2\int x^{2}\mathrm{d}x-2\int x^{2}\mathrm{d}x+\int x\mathrm{d}x$$

k\neq -1 uchun integral \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} boʻlgani uchun, \int x^{2}\mathrm{d}x integralni \frac{x^{3}}{3} bilan almashtiring. -2 ni \frac{x^{3}}{3} marotabaga ko'paytirish.

$$x^{2}+2x-x-\frac{2x^{3}}{3}-2\int x^{2}\mathrm{d}x+\int x\mathrm{d}x$$

k\neq -1 uchun integral \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} boʻlgani uchun, \int x^{2}\mathrm{d}x integralni \frac{x^{3}}{3} bilan almashtiring. -2 ni \frac{x^{3}}{3} marotabaga ko'paytirish.

$$x^{2}+2x-x-\frac{2x^{3}}{3}-\frac{2x^{3}}{3}+\int x\mathrm{d}x$$

k\neq -1 uchun integral \int x^{k}\mathrm{d}x=\frac{x^{k+1}}{k+1} boʻlgani uchun, \int x\mathrm{d}x integralni \frac{x^{2}}{2} bilan almashtiring.
