factor a^3-4a^2+20a-125

factor

a^{3} - 4 a^{2} + 20 a - 125

(a - 5) (a^{2} + a + 25)

Solution steps

a^{3} - 4 a^{2} + 20 a - 125

Use the rational root theorem

= (a - 5) \frac{a ^{3} - 4 a ^{2} + 20 a - 125}{a - 5}

\frac{a ^{3} - 4 a ^{2} + 20 a - 125}{a - 5} = a^{2} + a + 25

= (a - 5) (a^{2} + a + 25)

\frac{1}{8} + \frac{1}{8} + \frac{1}{8}

9 y^{2} + 18 y - 16

8 x^{2} - 56 x = 0

\frac{1}{20} + \frac{1}{30}

6 + 3 y \leq 7 - 5 y
