Question

$(5c-1/x)^{2}+5(5x-1x)+b$. solve this please​

Answer 1

Let $5x \frac{-1}{x}=y$

squaring on both sides,

we get,

$\implies 5x\frac{-1}{x}^{2}=y^{2} \\ \implies y^{2}+5y+6 \\ \implies y^{2}+3y+2y+6 \\ \implies y(y+3)+2(y+3) \\ \implies(y+3),(y+2)$

Now,

put y=$5x\frac{-1}{x}$

$\implies [ 5x\frac{-1}{x}+3][5x\frac{-1}{x}×2]$
