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

simplify

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

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

Solution steps

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

Simplify

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

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

Apply the fraction rule:

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

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

Simplify

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

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

Apply the fraction rule:

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

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

Multiply the numbers:

2 \cdot 2 = 4

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

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

(1 + 2 i)^{5}

4 (sin^{4} (x) + cos^{4} (x))

(1 + i 3)^{5}

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

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