factor x^2+5x+4

factor

x^{2} + 5 x + 4

(x + 1) (x + 4)

Solution steps

x^{2} + 5 x + 4

Break the expression into groups

= (x^{2} + x) + (4 x + 4)

Factor out

x

from

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

Factor out

4

from

4 x + 4 : 4 (x + 1)

= x (x + 1) + 4 (x + 1)

Factor out common term

x + 1

= (x + 1) (x + 4)

\frac{1}{2} (x - 1) = 2 - \frac{1}{5} (x + 2)

\frac{x - 3}{18} = \frac{12}{9}

(- \frac{3}{6})^{2} (\frac{4}{3})^{2}

∣ 3 x + 5 ∣ + 2 < 1

∣ 3 x + 6 ∣ = - 9
