simplify (3x+4/5)(3x-4/5)

simplify

(3 x + \frac{4}{5}) (3 x - \frac{4}{5})

\frac{( 15 x + 4 ) ( 15 x - 4 )}{25}

Solution steps

(3 x + \frac{4}{5}) (3 x - \frac{4}{5})

Join

3 x + \frac{4}{5} : \frac{15 x + 4}{5}

= \frac{15 x + 4}{5} (3 x - \frac{4}{5})

Apply the fraction rule:

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

= \frac{( 15 x + 4 ) ( 3 x - \frac{4}{5} )}{5}

Simplify

(15 x + 4) (3 x - \frac{4}{5}) : \frac{( 15 x + 4 ) ( 15 x - 4 )}{5}

= \frac{\frac{( 15 x + 4 ) ( 15 x - 4 )}{5}}{5}

Apply the fraction rule:

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

= \frac{( 15 x + 4 ) ( 15 x - 4 )}{5 \cdot 5}

Multiply the numbers:

5 \cdot 5 = 25

= \frac{( 15 x + 4 ) ( 15 x - 4 )}{25}

cos^{2} (x) + sin^{2} (x)

24 e^{- 20 x} + 20 (\frac{6}{5} - \frac{6}{5} e^{- 20 x})

y (6 y^{2} - x - 1) d x + 2 x d y

(x y^{2} + b x^{2} y) + (x + y) x^{2} \frac{d y}{d x}

a (- 2, - 3) b (- 4, - 5) c (- 1, - 6)
