factor

2 x^{2} + x - 28

(2 x - 7) (x + 4)

Solution steps

2 x^{2} + x - 28

Break the expression into groups

= (2 x^{2} - 7 x) + (8 x - 28)

Factor out

x

from

2 x^{2} - 7 x : x (2 x - 7)

Factor out

4

from

8 x - 28 : 4 (2 x - 7)

= x (2 x - 7) + 4 (2 x - 7)

2 x - 7

= (2 x - 7) (x + 4)

s^{2} - 1 > 1

6 - 3 x \leq 12

x^{3} - 16 x \leq 0

6 x^{2} - 21 x + 15

\frac{b - 1}{4} + \frac{2 b - 3}{2} = b - \frac{1}{2}
