factor

9 y^{2} - 2 y - 7

(9 y + 7) (y - 1)

= (9 y^{2} + 7 y) + (- 9 y - 7)

Factor out

y

from

9 y^{2} + 7 y : y (9 y + 7)

Factor out

- 1

from

- 9 y - 7 : - (9 y + 7)

= y (9 y + 7) - (9 y + 7)

9 k^{2} + 24 k + 18 = 0

\frac{( n + 4 ) !}{n !}

lo g_{3} (3^{- 2}) = x

f = (- 3)^{2} - 5

x^{2} + 3 x - 28 \leq 0
