factor x^2+16x-36

factor

x^{2} + 16 x - 36

(x - 2) (x + 18)

Solution steps

x^{2} + 16 x - 36

Break the expression into groups

= (x^{2} - 2 x) + (18 x - 36)

Factor out

x

from

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

Factor out

18

from

18 x - 36 : 18 (x - 2)

= x (x - 2) + 18 (x - 2)

Factor out common term

x - 2

= (x - 2) (x + 18)

\frac{1}{\frac{1}{x + 1} + 1}

\frac{1}{2}

\frac{- 25}{( - 5 )}

(- 1) + 4

(\frac{1}{cos ( x )})^{2}
