3 tan^{4} (x) - 10 tan^{2} (x) + 3

Schritte zur Lösung

(3 tan^{2} (x) - 1) (tan^{2} (x) - 3)

Apply FOIL method

(3 tan^{2} (x) - 1) (tan^{2} (x) - 3) : 3 tan^{4} (x) - 10 tan^{2} (x) + 3

= 3 tan^{4} (x) - 10 tan^{2} (x) + 3

e x p an d (x - 2 i) (x + 2 i)

e x p an d (x^{\frac{2}{3}} - 1)^{2}

e x p an d cot (x) + cos (x) (tan (x) - tan (\frac{x}{2}))

e x p an d (- 4 b + 2 x^{\frac{21}{5}}) (4 x^{3})

e x p an d (x y^{2} - 4 x^{2} y^{3} + 5 x^{3} y + 4 x^{2}) l e f t (- 2 x^{3} y)
