simplify (x^2+1)(x^2-2x^a-2x^a+2-x^2+2009)

simplify

(x^{2} + 1) (x^{2} - 2 x^{a} - 2 x^{a} + 2 - x^{2} + 2009)

(x^{2} + 1) (- 4 x^{a} + 2011)

Solution steps

(x^{2} + 1) (x^{2} - 2 x^{a} - 2 x^{a} + 2 - x^{2} + 2009)

Add similar elements:

- 2 x^{a} - 2 x^{a} = - 4 x^{a}

= (x^{2} + 1) (x^{2} - 4 x^{a} + 2 - x^{2} + 2009)

Group like terms

= (x^{2} + 1) (x^{2} - x^{2} - 4 x^{a} + 2 + 2009)

Add similar elements:

x^{2} - x^{2} = 0

= (x^{2} + 1) (- 4 x^{a} + 2 + 2009)

Add the numbers:

2 + 2009 = 2011

= (x^{2} + 1) (- 4 x^{a} + 2011)

(81 x^{- 2} 4 y^{16} z^{52})^{0} + 7

5 a^{2} - 20 b^{2}

(2 x + 3 y)^{3} + 2 (2 x + 3 y) + 1

(a + b)^{2} (a - b)^{3} - 2 a^{3}

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