simplify (x^4-9x^2+3+x)/(x+3)

simplify

\frac{x ^{4} - 9 x ^{2} + 3 + x}{x + 3}

x^{3} - 3 x^{2} + 1

Solution steps

\frac{x ^{4} - 9 x ^{2} + 3 + x}{x + 3}

Factor

x^{4} - 9 x^{2} + 3 + x : (x + 3) (x^{3} - 3 x^{2} + 1)

= \frac{( x + 3 ) ( x ^{3} - 3 x ^{2} + 1 )}{x + 3}

Cancel the common factor:

x + 3

= x^{3} - 3 x^{2} + 1

(- 5 + 12 i)^{2}

2 \cdot 12

\frac{4 x}{4 x}

(csc^{2} (x) - 1) sin^{2} (x)

(1 + \frac{0.1}{4})^{4} - 1
