expand (w(l-x)^2)/2

expand

\frac{w ( l - x ) ^{2}}{2}

\frac{l ^{2} w}{2} - lw x + \frac{w x ^{2}}{2}

Solution steps

\frac{w ( l - x ) ^{2}}{2}

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

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

Expand

w (l^{2} - 2 l x + x^{2}) : l^{2} w - 2 lw x + w x^{2}

= \frac{l ^{2} w - 2 lw x + w x ^{2}}{2}

Apply the fraction rule:

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

\frac{l ^{2} w - 2 lw x + w x ^{2}}{2} = \frac{l ^{2} w}{2} - \frac{2 lw x}{2} + \frac{w x ^{2}}{2}

= \frac{l ^{2} w}{2} - \frac{2 lw x}{2} + \frac{w x ^{2}}{2}

Divide the numbers:

\frac{2}{2} = 1

= \frac{l ^{2} w}{2} - lw x + \frac{w x ^{2}}{2}

(- \frac{3}{4} x + y = - 1) (- 4)
