factor a^3-7a^2+7a+15

factor

a^{3} - 7 a^{2} + 7 a + 15

(a + 1) (a - 3) (a - 5)

Solution steps

a^{3} - 7 a^{2} + 7 a + 15

Use the rational root theorem

= (a + 1) \frac{a ^{3} - 7 a ^{2} + 7 a + 15}{a + 1}

\frac{a ^{3} - 7 a ^{2} + 7 a + 15}{a + 1} = a^{2} - 8 a + 15

= (a + 1) (a^{2} - 8 a + 15)

Factor

a^{2} - 8 a + 15 : (a - 3) (a - 5)

= (a + 1) (a - 3) (a - 5)

- 3 (x + 1)

\frac{6}{- 4 i}

ln (e^{- 2 y})

(9 - 3 i) + (5 + 6 i)

\frac{26 + 28 i}{2 + i}
