\frac{( 2.9 ) ^{2} - 9}{( 2.9 ) - 3}

5.9

Solution steps

\frac{2. 9 ^{2} - 9}{( 2.9 ) - 3}

Apply rule:

(a) = a

(2.9) = 2.9

= \frac{2. 9 ^{2} - 9}{2.9 - 3}

Factor

2. 9^{2} - 9 : (2.9 + 3) (2.9 - 3)

= \frac{( 2.9 + 3 ) ( 2.9 - 3 )}{2.9 - 3}

\frac{( 2.9 + 3 ) ( 2.9 - 3 )}{2.9 - 3} = \frac{5.9 ( - 0.1 )}{- 0.1}

= \frac{5.9 ( - 0.1 )}{- 0.1}

Cancel the common factor:

- 0.1

= 5.9
