factor a^3-5a^2-9a+45

factor

a^{3} - 5 a^{2} - 9 a + 45

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

Solution steps

a^{3} - 5 a^{2} - 9 a + 45

= (a^{3} - 5 a^{2}) + (- 9 a + 45)

Factor out

a^{2}

from

a^{3} - 5 a^{2} : a^{2} (a - 5)

Factor out

- 9

from

- 9 a + 45 : - 9 (a - 5)

= a^{2} (a - 5) - 9 (a - 5)

Factor out common term

a - 5

= (a - 5) (a^{2} - 9)

Factor

a^{2} - 9 : (a + 3) (a - 3)

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

p^{2} + 8 p + 12

3 5^{2} + x^{2} = 3 7^{2}

- 32 - \frac{3}{5} f = - 17

2 7^{\frac{1}{2}}

- 2 \cdot 3^{- (0)}
