simplify (-3x^2)/(4x+9)-(-4x^2)/(4x+9)

simplify

\frac{- 3 x ^{2}}{4 x + 9} - \frac{- 4 x ^{2}}{4 x + 9}

\frac{x ^{2}}{4 x + 9}

Solution steps

\frac{- 3 x ^{2}}{4 x + 9} - \frac{- 4 x ^{2}}{4 x + 9}

\frac{- 3 x ^{2}}{4 x + 9} = - \frac{3 x ^{2}}{4 x + 9}

- \frac{3 x ^{2}}{4 x + 9} - (- \frac{4 x ^{2}}{4 x + 9}) : \frac{x ^{2}}{4 x + 9}

= \frac{x ^{2}}{4 x + 9}

(x^{7})^{3}

2 - 5 \cdot 2 + 6^{2} + 9 - 2^{3}

\frac{3}{2 - 5}

9 \cdot 8 \cdot 7 \cdot 6 \cdot 5 \cdot 4 \cdot 3 \cdot 2 \cdot 1
