factor x^4+5x^3+4x+20

factor

x^{4} + 5 x^{3} + 4 x + 20

(x + 5) (x^{3} + 4)

Solution steps

x^{4} + 5 x^{3} + 4 x + 20

= (x^{4} + 5 x^{3}) + (4 x + 20)

Factor out

x^{3}

from

x^{4} + 5 x^{3} : x^{3} (x + 5)

Factor out

4

from

4 x + 20 : 4 (x + 5)

= x^{3} (x + 5) + 4 (x + 5)

Factor out common term

x + 5

= (x + 5) (x^{3} + 4)

2 (\frac{5}{13}) (\frac{12}{13})

r^{2} - 8 r = 0

(11 x^{\frac{1}{2} + 2}) 2 x

5445 + 0.345 - 45 \cdot 4997 (674 \cdot 447) = 0 \cdot 5 + 69

- 2 x^{2} - 4 x + 3 = 0
