x^{2} - 22 x + 72

(x - 4) (x - 18)

Solution steps

x^{2} - 22 x + 72

Break the expression into groups

= (x^{2} - 4 x) + (- 18 x + 72)

x

from

x^{2} - 4 x : x (x - 4)

Factor out

- 18

from

- 18 x + 72 : - 18 (x - 4)

= x (x - 4) - 18 (x - 4)

x - 4

= (x - 4) (x - 18)

(\frac{4 x}{y})^{2}

- 4 i \cdot 5 i

\frac{x}{2} = 9
