factor x^2-22x+121

factor

x^{2} - 22 x + 121

(x - 11)^{2}

Solution steps

x^{2} - 22 x + 121

Rewrite in the form of

a^{2} + 2 ab + b^{2} :

121 = 1 1^{2}

- 22 x = - 2 x \cdot 11

= x^{2} - 2 x \cdot 11 + 1 1^{2}

Apply Perfect Square Formula:

a^{2} - 2 ab + b^{2} = (a - b)^{2}

x^{2} - 2 x \cdot 11 + 1 1^{2} = (x - 11)^{2}

= (x - 11)^{2}

\frac{6}{3 x y} - \frac{5}{y ^{2}}

d^{3} + 12 = 14

x^{2} - 18 x + 65

- \frac{5}{9} - (- \frac{5}{6})

4 \geq 2 - 4 x
