factor x^4-4x^3-21x^2

factor

x^{4} - 4 x^{3} - 21 x^{2}

x^{2} (x + 3) (x - 7)

Solution steps

x^{4} - 4 x^{3} - 21 x^{2}

Factor out common term

x^{2} : x^{2} (x^{2} - 4 x - 21)

= x^{2} (x^{2} - 4 x - 21)

Factor

x^{2} - 4 x - 21 : (x + 3) (x - 7)

= x^{2} (x + 3) (x - 7)

4 lo g_{4} (5) + 5 lo g_{4} (x)

x^{4} - 10 x^{2} \cdot y^{2} + 25 y^{4}

(x^{2} + 16) (x + 4) (x - 4)

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

x^{4} - 4 y^{3} + 2 x^{2} - 2 x^{2} \cdot y^{3}
