factor

x^{2} + 12 x - 45

(x - 3) (x + 15)

Solution steps

x^{2} + 12 x - 45

Break the expression into groups

= (x^{2} - 3 x) + (15 x - 45)

Factor out

x

from

x^{2} - 3 x : x (x - 3)

Factor out

15

from

15 x - 45 : 15 (x - 3)

= x (x - 3) + 15 (x - 3)

= (x - 3) (x + 15)

- n < 2 or 2 n - 3 > 5

(\frac{8 ^{4}}{1 0 ^{4}})^{- \frac{1}{4}}

\frac{23}{17} - \frac{5}{2}

x^{- \frac{1}{3}} (x^{\frac{7}{6}} - x^{\frac{3}{4}})

\frac{1}{7} \cdot \frac{2}{9}
