7 n^{2} + 20 n - 32

(7 n - 8) (n + 4)

Solution steps

7 n^{2} + 20 n - 32

Break the expression into groups

= (7 n^{2} - 8 n) + (28 n - 32)

Factor out

n

from

7 n^{2} - 8 n : n (7 n - 8)

Factor out

4

from

28 n - 32 : 4 (7 n - 8)

= n (7 n - 8) + 4 (7 n - 8)

7 n - 8

= (7 n - 8) (n + 4)

x (x + 4) = - 20

(5 + 3) j = 48

- 3 x^{2} + 18 x = 0

- \frac{24}{( 4 ( - 1 ) + 1 ) ^{2}}

∣ x ∣ = x^{2} - 1
