factor n^2-10n+21

factor

n^{2} - 10 n + 21

(n - 3) (n - 7)

Solution steps

n^{2} - 10 n + 21

Break the expression into groups

= (n^{2} - 3 n) + (- 7 n + 21)

Factor out

n

from

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

Factor out

- 7

from

- 7 n + 21 : - 7 (n - 3)

= n (n - 3) - 7 (n - 3)

Factor out common term

n - 3

= (n - 3) (n - 7)

\frac{25 x ^{2} y ^{4}}{25 x y}

\frac{- 2 ( x - 3 )}{6} > - 2

X + 4 = 12 - X

- 3 x^{2} + 1 = 0

x^{2} - 16 > 0
