simplify 2(x^2-r^2)((x+r)/(2x))

simplify

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

\frac{( x ^{2} - r ^{2} ) ( x + r )}{x}

Solution steps

2 (x^{2} - r^{2}) (\frac{x + r}{2 x})

Apply rule:

(a) = a

(\frac{x + r}{2 x}) = \frac{x + r}{2 x}

= 2 (x^{2} - r^{2}) \frac{x + r}{2 x}

Apply the fraction rule:

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

= \frac{2 ( x ^{2} - r ^{2} ) ( x + r )}{2 x}

Cancel the common factor:

2

= \frac{( x ^{2} - r ^{2} ) ( x + r )}{x}

- \frac{1}{4} \cdot 3

lo g_{2} (3^{2})

6 x \cdot x^{2}

\frac{51}{68}
