simplify ((-3.1)^2-9)/((-3.1)+3)

simplify

\frac{( - 3.1 ) ^{2} - 9}{( - 3.1 ) + 3}

- 6.1

Solution steps

\frac{( - 3.1 ) ^{2} - 9}{( - 3.1 ) + 3}

Apply rule:

(- a) = - a

(- 3.1) = - 3.1

= \frac{( - 3.1 ) ^{2} - 9}{- 3.1 + 3}

Factor

(- 3.1)^{2} - 9 : (- 3.1 + 3) (- 3.1 - 3)

= \frac{( - 3.1 + 3 ) ( - 3.1 - 3 )}{- 3.1 + 3}

\frac{( - 3.1 + 3 ) ( - 3.1 - 3 )}{- 3.1 + 3} = \frac{- 0.1 ( - 6.1 )}{- 0.1}

= \frac{- 0.1 ( - 6.1 )}{- 0.1}

Cancel the common factor:

- 0.1

= - 6.1

\frac{2}{\frac{1}{x + 5}} - 5

\frac{y}{6 + y}

1 - 9 x^{2} + 24 x y - 16 y^{2}

(5 m - 4) (- 2 m + 7)

4 \cdot 6 \cdot 5
