factor a^2+9-6a

factor

a^{2} + 9 - 6 a

(a - 3)^{2}

Solution steps

a^{2} + 9 - 6 a

Write in the standard form

= a^{2} - 6 a + 9

Rewrite in the form of

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

9 = 3^{2}

- 6 a = - 2 a \cdot 3

= a^{2} - 2 a \cdot 3 + 3^{2}

Apply Perfect Square Formula:

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

a^{2} - 2 a \cdot 3 + 3^{2} = (a - 3)^{2}

= (a - 3)^{2}

\frac{∣ x - 5 ∣}{x} + \frac{x - 2}{x + 1} \leq 0

\frac{4}{x} - 3 > \frac{2 x}{x} - 7

(72 - 33) (46 + 312)

(\frac{2}{9})^{- 2}
