factor

a^{2} + a - 380

(a - 19) (a + 20)

Solution steps

a^{2} + a - 380

Break the expression into groups

= (a^{2} - 19 a) + (20 a - 380)

Factor out

a

from

a^{2} - 19 a : a (a - 19)

Factor out

20

from

20 a - 380 : 20 (a - 19)

= a (a - 19) + 20 (a - 19)

Factor out common term

a - 19

= (a - 19) (a + 20)

6 x^{2} - 12 x > x^{2} + 17 x

(x - 2) (x + 4) \geq 0

\frac{x + 1}{x + 3} \geq 0

- 3 x^{2} + 6 x - 1 = 0

\frac{15}{10} = \frac{x}{4}
