b^2-b-30=y eching

$$b ^ { 2 } - b - 30 = y$$

y uchun yechish

$$y=\left(b-6\right)\left(b+5\right)$$

Yechim qadamlari

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$y=b^{2}-b-30$$

b uchun yechish (complex solution)

$$b=\frac{\sqrt{4y+121}+1}{2}$$

$$b=\frac{-\sqrt{4y+121}+1}{2}$$

b uchun yechish

$$b=\frac{\sqrt{4y+121}+1}{2}$$

$$b=\frac{-\sqrt{4y+121}+1}{2}\text{, }y\geq -\frac{121}{4}$$
