simplify (x+1/2)(x-11/2)

simplify

(x + \frac{1}{2}) (x - \frac{11}{2})

\frac{( 2 x + 1 ) ( 2 x - 11 )}{4}

Solution steps

(x + \frac{1}{2}) (x - \frac{11}{2})

Simplify

x + \frac{1}{2} : \frac{2 x + 1}{2}

= \frac{2 x + 1}{2} (x - \frac{11}{2})

Apply the fraction rule:

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

= \frac{( 2 x + 1 ) ( x - \frac{11}{2} )}{2}

Simplify

(2 x + 1) (x - \frac{11}{2}) : \frac{( 2 x + 1 ) ( x \cdot 2 - 11 )}{2}

= \frac{\frac{( 2 x + 1 ) ( x \cdot 2 - 11 )}{2}}{2}

Apply the fraction rule:

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

= \frac{( 2 x + 1 ) ( x \cdot 2 - 11 )}{2 \cdot 2}

Multiply the numbers:

2 \cdot 2 = 4

= \frac{( 2 x + 1 ) ( x \cdot 2 - 11 )}{4}

= \frac{( 2 x + 1 ) ( 2 x - 11 )}{4}

\frac{( 1 - x ) ^{2}}{( 1 + x ) ( 1 + x ^{2} )}

(a - \frac{1}{a}) (a + \frac{1}{a})

- 2 (3 - 5)

(5^{3})^{6}
