factor

c^{2} - 3 c - 28

(c + 4) (c - 7)

Solution steps

c^{2} - 3 c - 28

Break the expression into groups

= (c^{2} + 4 c) + (- 7 c - 28)

Factor out

c

from

c^{2} + 4 c : c (c + 4)

Factor out

- 7

from

- 7 c - 28 : - 7 (c + 4)

= c (c + 4) - 7 (c + 4)

c + 4

= (c + 4) (c - 7)

∣ 5 - 6 x ∣ \geq 7

\frac{5 !}{( 5 - 2 ) ! 2 !}

8 x^{2} - 21 x - 9

ln (7) = 3 y

5 z = - 60
