simplify x^2+3x-x^3-(-8)x^2+x-9-5x^3-x^2+17

simplify

x^{2} + 3 x - x^{3} - (- 8) x^{2} + x - 9 - 5 x^{3} - x^{2} + 17

- 6 x^{3} + 8 x^{2} + 4 x + 8

Solution steps

x^{2} + 3 x - x^{3} - (- 8) x^{2} + x - 9 - 5 x^{3} - x^{2} + 17

Group like terms

= - x^{3} - 5 x^{3} + x^{2} - (- 8) x^{2} - x^{2} + 3 x + x - 9 + 17

Add similar elements:

- x^{3} - 5 x^{3} = - 6 x^{3}

= - 6 x^{3} + x^{2} - (- 8) x^{2} - x^{2} + 3 x + x - 9 + 17

Add similar elements:

x^{2} - (- 8) x^{2} - x^{2} = 8 x^{2}

= - 6 x^{3} + 8 x^{2} + 3 x + x - 9 + 17

Add similar elements:

3 x + x = 4 x

= - 6 x^{3} + 8 x^{2} + 4 x - 9 + 17

Add the numbers:

- 9 + 17 = 8

= - 6 x^{3} + 8 x^{2} + 4 x + 8

6 \cdot 27

\frac{( 2 x ^{3} - 3 x ^{2} + 1 ) ( x + 2 )}{x ^{2} - 4}

(- 3 x^{3} y^{2}) (5 x^{5} y^{4})^{2}

(27 x^{3})^{\frac{1}{3}}

\frac{x ^{2} + x - 12}{x ^{2} - 6 x + 9}
