simplify (9x^2-9)/((x-1))

Solution

simplify

\frac{9 x ^{2} - 9}{( x - 1 )}

Solution

9 x + 9

Solution steps

\frac{9 x ^{2} - 9}{x - 1}

Factor

9 x^{2} - 9 : 9 (x^{2} - 1)

= \frac{9 ( x ^{2} - 1 )}{x - 1}

Factor

x^{2} - 1 : (x + 1) (x - 1)

= \frac{9 ( x + 1 ) ( x - 1 )}{x - 1}

Cancel the common factor:

x - 1

= 9 (x + 1)

Expand

9 (x + 1) : 9 x + 9

= 9 x + 9
