factor x^2-18x+81-y^2

factor

x^{2} - 18 x + 81 - y^{2}

(x - 9 + y) (x - 9 - y)

Solution steps

x^{2} - 18 x + 81 - y^{2}

Factor

x^{2} - 18 x + 81 : (x - 9)^{2}

= (x - 9)^{2} - y^{2}

Apply Difference of Two Squares Formula:

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

(x - 9)^{2} - y^{2} = ((x - 9) + y) ((x - 9) - y)

= ((x - 9) + y) ((x - 9) - y)

Apply rule:

(a) = a

(x - 9) = x - 9

= (x - 9 + y) (x - 9 - y)

5 x - 9 + 9 x

\frac{( 6 x ^{3} - 13 x ^{2} + 18 x - 8 )}{( 3 x - 2 )}

\frac{( 1 1 ^{p + 2} - 1 1 ^{p} )}{( 1 1 ^{p + 1} + 1 1 ^{p} )}

(a^{2} \cdot b - a \cdot b^{2})^{3}

(m + 3 n) 2
