factor n^2-2n-15

factor

n^{2} - 2 n - 15

(n + 3) (n - 5)

Solution steps

n^{2} - 2 n - 15

Break the expression into groups

= (n^{2} + 3 n) + (- 5 n - 15)

Factor out

n

from

n^{2} + 3 n : n (n + 3)

Factor out

- 5

from

- 5 n - 15 : - 5 (n + 3)

= n (n + 3) - 5 (n + 3)

Factor out common term

n + 3

= (n + 3) (n - 5)

6 x^{3} y + 48 y^{4}

1 + 14 - (14 - 1)

x^{2} + 18 x + 81 = 25

\frac{7}{100} x^{2} - \frac{y}{121}

\frac{\frac{1}{2}}{- \frac{1}{2}}
