factor

15 x^{2} - 28 x - 32

(5 x + 4) (3 x - 8)

Solution steps

15 x^{2} - 28 x - 32

Break the expression into groups

= (15 x^{2} + 12 x) + (- 40 x - 32)

Factor out

3 x

from

15 x^{2} + 12 x : 3 x (5 x + 4)

Factor out

- 8

from

- 40 x - 32 : - 8 (5 x + 4)

= 3 x (5 x + 4) - 8 (5 x + 4)

Factor out common term

5 x + 4

= (5 x + 4) (3 x - 8)

- x^{2} - 2 x + 8

10 x^{3} y^{2} - 2 x y^{2} + 14 x y

\frac{5 !}{3 ! 2 !}

- 9 (\frac{1}{8} - \frac{5}{4}) - \frac{5}{9}

0.1 x + 4.75 = - 1.5
