factor a^2-6a+9-y^2

factor

a^{2} - 6 a + 9 - y^{2}

(y + a - 3) (- y + a - 3)

Solution steps

a^{2} - 6 a + 9 - y^{2}

Factor

a^{2} - 6 a + 9 : (a - 3)^{2}

= (a - 3)^{2} - y^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(a - 3)^{2} - y^{2} = ((a - 3) + y) ((a - 3) - y)

= ((a - 3) + y) ((a - 3) - y)

Apply rule:

(a) = a

(a - 3) = a - 3

= (a - 3 + y) (a - 3 - y)

= (y + a - 3) (- y + a - 3)

p^{2} - (r + 2)^{2}

\frac{( x ^{2} - 5 x - 6 )}{( x - 6 )}

\frac{b ^{6}}{b ^{4}}

\frac{3 - 1}{1 - 3}

\frac{1}{\frac{3}{x}}
