simplify ((-2.9)^2-9)/((-2.9)+3)

simplify

\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{0.1 ( - 5.9 )}{0.1}

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

Cancel the common factor:

0.1

= - 5.9

(2 a + b - c)^{2} - (a + b)^{2}

(3 x^{4} - 5 x^{3} y)^{3}

\frac{63}{5}

- 6 y + 6 y

\frac{5 p ^{7}}{25 p ^{4}}
