expand ((4x+13)^2)/4

Solution

expand

\frac{( 4 x + 13 ) ^{2}}{4}

Solution

4 x^{2} + 26 x + \frac{169}{4}

Solution steps

\frac{( 4 x + 13 ) ^{2}}{4}

(4 x + 13)^{2} = 16 x^{2} + 104 x + 169

= \frac{16 x ^{2} + 104 x + 169}{4}

Apply the fraction rule:

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

\frac{16 x ^{2} + 104 x + 169}{4} = \frac{16 x ^{2}}{4} + \frac{104 x}{4} + \frac{169}{4}

= \frac{16 x ^{2}}{4} + \frac{104 x}{4} + \frac{169}{4}

Divide the numbers:

\frac{16}{4} = 4

= 4 x^{2} + \frac{104 x}{4} + \frac{169}{4}

Divide the numbers:

\frac{104}{4} = 26

= 4 x^{2} + 26 x + \frac{169}{4}
