expand (x^2+3)(x^4-3x^2+9)

expand

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

x^{6} + 27

Solution steps

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

Distribute parentheses

= x^{2} x^{4} + x^{2} (- 3 x^{2}) + x^{2} \cdot 9 + 3 x^{4} + 3 (- 3 x^{2}) + 3 \cdot 9

Simplify

x^{2} x^{4} + x^{2} (- 3 x^{2}) + x^{2} \cdot 9 + 3 x^{4} + 3 (- 3 x^{2}) + 3 \cdot 9 : x^{6} + 27

= x^{6} + 27

- \frac{5}{3} \cdot (- \frac{1}{8})

1 0^{- 3.4}

(- 1 + 2 x^{2})^{13}

(x^{2} - 2 x) (2 x + 3)

(- (\frac{1 - 2 x}{2})^{\frac{1}{2}})^{2}
