factor y^2-22y+121

factor

y^{2} - 22 y + 121

(y - 11)^{2}

Solution steps

y^{2} - 22 y + 121

Rewrite in the form of

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

121 = 1 1^{2}

- 22 y = - 2 y \cdot 11

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

Apply Perfect Square Formula:

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

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

= (y - 11)^{2}

t^{2} + 7 t + 10

\frac{2 x ^{4} y ^{3} z ^{2}}{10 x ^{- 2} y ^{- 1} z}

- 7 h + 2 (- 4 h + 5) > - 4 h + 1 + 10

\frac{5}{2 x - 1} \geq \frac{1}{x - 2}

8 = x^{2} - 4
