expand ((2x+5)^2)/4

Solution

expand

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

Solution

x^{2} + 5 x + \frac{25}{4}

Solution steps

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

(2 x + 5)^{2} = 4 x^{2} + 20 x + 25

= \frac{4 x ^{2} + 20 x + 25}{4}

Apply the fraction rule:

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

\frac{4 x ^{2} + 20 x + 25}{4} = \frac{4 x ^{2}}{4} + \frac{20 x}{4} + \frac{25}{4}

= \frac{4 x ^{2}}{4} + \frac{20 x}{4} + \frac{25}{4}

Divide the numbers:

\frac{4}{4} = 1

= x^{2} + \frac{20 x}{4} + \frac{25}{4}

Divide the numbers:

\frac{20}{4} = 5

= x^{2} + 5 x + \frac{25}{4}
