Question

f(x)=3x-1/x - (5x-x^2)^2

Answer 1

Respuesta:

Explicación paso a paso:

$f(x)=3x-\frac{1}{x}-(5x-x^{2} )^{2}$

$f(x)=3x-\frac{1}{x}-(25x^{2}-2(5x)(x^{2}) +x^{4} )$

$f(x)=3x-\frac{1}{x}-(25x^{2}-10x^{3} +x^{4} )$

$f(x)=3x-\frac{1}{x}-25x^{2}+10x^{3} +x^{4} )$

$f(x)=\frac{3x^{2}-1-25x^{3}+10x^{4} +x^{5}}{x}$

$f(x)=\frac{x^{5}+10x^{4}-25x^{3}+3x^{2}-1}{x}$
