factor

- 7 v^{2} - 25 v - 12

- (7 v + 4) (v + 3)

Solution steps

- 7 v^{2} - 25 v - 12

Break the expression into groups

= (- 7 v^{2} - 4 v) + (- 21 v - 12)

Factor out

- v

from

- 7 v^{2} - 4 v : - v (7 v + 4)

Factor out

- 3

from

- 21 v - 12 : - 3 (7 v + 4)

= - v (7 v + 4) - 3 (7 v + 4)

Factor out common term

7 v + 4

= (7 v + 4) (- v - 3)

Factor

- v - 3 : - (v + 3)

= (7 v + 4) (- (v + 3))

a (- b) = - ab

(7 v + 4) (- (v + 3)) = - (7 v + 4) (v + 3)

= - (7 v + 4) (v + 3)

4 x - 2 = 18

2^{- 1} \cdot 2^{- 3}

9 x - 8 + 6 x + 5 = 180

x^{2} = x + 6
