factor j^2-2j-3

factor

j^{2} - 2 j - 3

(j + 1) (j - 3)

Solution steps

j^{2} - 2 j - 3

Break the expression into groups

= (j^{2} + j) + (- 3 j - 3)

Factor out

j

from

j^{2} + j : j (j + 1)

Factor out

- 3

from

- 3 j - 3 : - 3 (j + 1)

= j (j + 1) - 3 (j + 1)

Factor out common term

j + 1

= (j + 1) (j - 3)

9 x^{2} < 25

k^{3} + 6 k^{2} + 11 k + 6

- \frac{35}{2} (\frac{1}{100 0 ^{2}}) + \frac{35}{2}

\frac{x + 13}{5 + x} \leq 2

7 < 3 x - 2 < 13
