expand 1/2 (x-11)(6+2x-16)

expand

\frac{1}{2} (x - 11) (6 + 2 x - 16)

x^{2} - 16 x + 55

Solution steps

\frac{1}{2} (x - 11) (6 + 2 x - 16)

Expand

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

= (\frac{x}{2} - \frac{11}{2}) (6 + 2 x - 16)

Distribute parentheses

= \frac{x}{2} \cdot 6 + \frac{x}{2} \cdot 2 x + \frac{x}{2} (- 16) - \frac{11}{2} \cdot 6 - \frac{11}{2} \cdot 2 x - \frac{11}{2} (- 16)

Simplify

\frac{x}{2} \cdot 6 + \frac{x}{2} \cdot 2 x + \frac{x}{2} (- 16) - \frac{11}{2} \cdot 6 - \frac{11}{2} \cdot 2 x - \frac{11}{2} (- 16) : x^{2} - 16 x + 55

= x^{2} - 16 x + 55

(2 - 4 x + 3)^{2}

\frac{( 3 x ^{2} + 4 )}{( x ^{2} + 1 ) ^{2}}

411 (23 + 62)

(sin (x) + 3)^{2}

(x^{2} + 3 x y + 2 y^{2}) d y
