expand (derivative of 4(x-1^2))/2

expand

\frac{\frac{d}{d x} ( 4 ( x - 1 ) ^{2} )}{2}

\frac{\frac{d}{d x} ( 4 x ^{2} - 8 x + 4 )}{2}

Solution steps

\frac{\frac{d}{d x} ( 4 ( x - 1 ) ^{2} )}{2}

(x - 1)^{2} = x^{2} - 2 x + 1

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

Expand

4 (x^{2} - 2 x + 1) : 4 x^{2} - 8 x + 4

= \frac{\frac{d}{d x} ( 4 x ^{2} - 8 x + 4 )}{2}

\frac{1}{( ( s + a ) ( s + b ) )}

\frac{x ( 3 - 4 x )}{5 + 7 x ^{2}}

\frac{x ^{2} + y ^{2}}{( x + y ) ^{2}}

(y + z)^{2}
