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

simplify

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

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

Solution steps

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

Join

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

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

Apply the fraction rule:

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

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

Simplify

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

- \frac{x ( x + 1 ) ( x + 10 )}{x + 5}

3 + 3 (x + \frac{π}{4})

(r + d r)^{3}

2 3 + 5 + 13 + 48 = a + b

(3 x + 2 e)^{3}
