simplify ((2x-10)\times (2x+10))/(x^2-25)

simplify

\frac{( 2 x - 10 ) \cdot ( 2 x + 10 )}{x ^{2} - 25}

4

Solution steps

\frac{( 2 x - 10 ) ( 2 x + 10 )}{x ^{2} - 25}

Factor

2 x - 10 : 2 (x - 5)

= \frac{2 ( x - 5 ) ( 2 x + 10 )}{x ^{2} - 25}

Factor

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

= \frac{2 ( x - 5 ) ( 2 x + 10 )}{( x + 5 ) ( x - 5 )}

Cancel the common factor:

x - 5

= \frac{2 ( 2 x + 10 )}{x + 5}

Factor

2 x + 10 : 2 (x + 5)

= \frac{2 \cdot 2 ( x + 5 )}{x + 5}

Cancel the common factor:

x + 5

= 2 \cdot 2

Multiply the numbers:

2 \cdot 2 = 4

= 4

\frac{4}{7} \times \frac{3}{6}

\frac{9}{6} \times \frac{4}{5}

218 + 58 - 50

(1 + \frac{0.043}{4})^{44} - 1

\frac{1}{( - 8 ) ^{- 2}}
