factor

2 x^{2} - 3 x - 20

(2 x + 5) (x - 4)

Solution steps

2 x^{2} - 3 x - 20

Break the expression into groups

= (2 x^{2} + 5 x) + (- 8 x - 20)

Factor out

x

from

2 x^{2} + 5 x : x (2 x + 5)

Factor out

- 4

from

- 8 x - 20 : - 4 (2 x + 5)

= x (2 x + 5) - 4 (2 x + 5)

Factor out common term

2 x + 5

= (2 x + 5) (x - 4)

16 x + 2 = 36 x - 6

\frac{x}{6} + x = \frac{5}{12}

2 x + 10 < 0

0 = x + x^{2}

3 t^{2} - 12 t + 9 = 0
