factor n^2-3n-28

factor

n^{2} - 3 n - 28

(n + 4) (n - 7)

Solution steps

n^{2} - 3 n - 28

Break the expression into groups

= (n^{2} + 4 n) + (- 7 n - 28)

Factor out

n

from

n^{2} + 4 n : n (n + 4)

Factor out

- 7

from

- 7 n - 28 : - 7 (n + 4)

= n (n + 4) - 7 (n + 4)

Factor out common term

n + 4

= (n + 4) (n - 7)

- 10 = 4 x

e^{- \frac{5}{5}}

\frac{1}{3 ^{2}}

\frac{- 9}{- 3}

∣ 4 y - 5 ∣ \geq 12
