expand ((5x+4)(5x-4))/(25)

expand

\frac{( 5 x + 4 ) ( 5 x - 4 )}{25}

x^{2} - \frac{16}{25}

Solution steps

\frac{( 5 x + 4 ) ( 5 x - 4 )}{25}

Expand

(5 x + 4) (5 x - 4) : 25 x^{2} - 16

= \frac{25 x ^{2} - 16}{25}

Apply the fraction rule:

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

\frac{25 x ^{2} - 16}{25} = \frac{25 x ^{2}}{25} - \frac{16}{25}

= \frac{25 x ^{2}}{25} - \frac{16}{25}

Divide the numbers:

\frac{25}{25} = 1

= x^{2} - \frac{16}{25}

(x cos (y) - 2 y) d y

4 (x^{2} + 3 x - 2)^{3}

\frac{6 ( 2 - θ ^{3} )}{3 - 2 θ}

(a + b + c + d + 1)^{3}

(2 e^{x} - 3)^{2}
