expand ((15x-8)(15x+8))/9

expand

\frac{( 15 x - 8 ) ( 15 x + 8 )}{9}

25 x^{2} - \frac{64}{9}

Solution steps

\frac{( 15 x - 8 ) ( 15 x + 8 )}{9}

Expand

(15 x - 8) (15 x + 8) : 225 x^{2} - 64

= \frac{225 x ^{2} - 64}{9}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{225 x ^{2} - 64}{9} = \frac{225 x ^{2}}{9} - \frac{64}{9}

= \frac{225 x ^{2}}{9} - \frac{64}{9}

Divide the numbers:

\frac{225}{9} = 25

= 25 x^{2} - \frac{64}{9}

\frac{1}{( x + 1 ) ^{3} ( x - 2 )}

(6 y - 24 x y^{5}) d x + (9 x - 56 x^{2} y^{4}) y^{^{'}}

- \frac{( 1 + y ) ( - 1 - 2 x - 2 x y )}{3 + x + 6 y + 3 y ^{2}}

e^{x} \cdot (sin (x + y) + cos (x + y) + 1)

\frac{d}{d t} ((x) (t^{2} + 6))
