factor 15y^4+5y^2-20y

factor

15 y^{4} + 5 y^{2} - 20 y

5 y (y - 1) (3 y^{2} + 3 y + 4)

Solution steps

15 y^{4} + 5 y^{2} - 20 y

Factor out common term

5 y : 5 y (3 y^{3} + y - 4)

= 5 y (3 y^{3} + y - 4)

Factor

3 y^{3} + y - 4 : (y - 1) (3 y^{2} + 3 y + 4)

= 5 y (y - 1) (3 y^{2} + 3 y + 4)

- (\frac{3}{5})^{- 2}

2 x + 3 y^{5} x - 1

(m + n)^{4}

f (z) = \frac{z ^{3} - 8}{z ^{2} + 2 z + 4}

\frac{4}{3} - \frac{5}{9}
