y=3(x+1)(x-4) eching

$$y = 3 ( x + 1 ) ( x - 4 )$$

y uchun yechish

$$y=3\left(x-4\right)\left(x+1\right)$$

Yechim qadamlari

3 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$y=\left(3x+3\right)\left(x-4\right)$$

3x+3 ga x-4 ni ko‘paytirish orqali distributiv xususiyatdan foydalaning va ifoda sifatida birlashtiring.

$$y=3x^{2}-9x-12$$

x uchun yechish (complex solution)

$$x=\frac{\sqrt{12y+225}}{6}+\frac{3}{2}$$

$$x=-\frac{\sqrt{12y+225}}{6}+\frac{3}{2}$$

x uchun yechish

$$x=\frac{\sqrt{12y+225}}{6}+\frac{3}{2}$$

$$x=-\frac{\sqrt{12y+225}}{6}+\frac{3}{2}\text{, }y\geq -\frac{75}{4}$$
