factor 49x^4-14x^3-28x

factor

49 x^{4} - 14 x^{3} - 28 x

7 x (7 x^{3} - 2 x^{2} - 4)

Solution steps

49 x^{4} - 14 x^{3} - 28 x

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

x^{3} = x^{2} x

= 49 x^{3} x - 14 x^{2} x - 28 x

Rewrite

49

7 \cdot 7

Rewrite

14

7 \cdot 2

= 7 \cdot 7 x^{3} x - 7 \cdot 2 x^{2} x - 7 \cdot 4 x

Factor out common term

7 x

= 7 x (7 x^{3} - 2 x^{2} - 4)

- k + 3 k

(t - 6) (t + 6) = (t - 2) (t - 4)

\frac{1}{16 a} + \frac{5}{12 b} - \frac{9}{10 b ^{3}}

18 + 72 - 2

x^{2} - 5 x + 6 < 0
