expand-(4(-2x^2+5))/(7x-9)

expand

- \frac{4 ( - 2 x ^{2} + 5 )}{7 x - 9}

- \frac{- 8 x ^{2} + 20}{7 x - 9}

Solution steps

- \frac{4 ( - 2 x ^{2} + 5 )}{7 x - 9}

Expand

4 (- 2 x^{2} + 5) : - 8 x^{2} + 20

= - \frac{- 8 x ^{2} + 20}{7 x - 9}

y^{2 d t + (2 y t + 1) d y}

4 (4 X^{3} + 2 X^{2} - 5 X)^{2}

(1 + y^{2}) (e^{2 x} - e^{y})

\frac{4 - x ^{2}}{2}

x (1 - cos (1) sin (1))
