factor 2n^2+n-10

factor

2 n^{2} + n - 10

(n - 2) (2 n + 5)

Solution steps

2 n^{2} + n - 10

Break the expression into groups

= (2 n^{2} - 4 n) + (5 n - 10)

Factor out

2 n

from

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

Factor out

5

from

5 n - 10 : 5 (n - 2)

= 2 n (n - 2) + 5 (n - 2)

Factor out common term

n - 2

= (n - 2) (2 n + 5)

\frac{x}{2} - \frac{5}{2} \leq \frac{x}{3} + 1

(5 a)^{- 2}

a^{2} - 15 a + 36

- 2 ∣ 4 n ∣ + 10 = - 6

x^{2} - 10 x \leq 200
