factor 2d^2-d-15

factor

2 d^{2} - d - 15

(2 d + 5) (d - 3)

Solution steps

2 d^{2} - d - 15

Break the expression into groups

= (2 d^{2} + 5 d) + (- 6 d - 15)

Factor out

d

from

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

Factor out

- 3

from

- 6 d - 15 : - 3 (2 d + 5)

= d (2 d + 5) - 3 (2 d + 5)

Factor out common term

2 d + 5

= (2 d + 5) (d - 3)

(7 x - 3)^{2} = 9

\frac{\frac{π}{8}}{2}

\frac{6}{3} - \frac{1}{6}

k - 9 = 21

0 = x^{2} - 5 x - 7
