expand (x+7/2)^2

Solution

expand

(x + \frac{7}{2})^{2}

Solution

\frac{4 x ^{2} + 28 x + 49}{4}

Solution steps

(x + \frac{7}{2})^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(x + \frac{7}{2})^{2} = x^{2} + 2 x \frac{7}{2} + (\frac{7}{2})^{2}

= x^{2} + 2 x \frac{7}{2} + (\frac{7}{2})^{2}

Simplify

x^{2} + 2 x \frac{7}{2} + (\frac{7}{2})^{2} : \frac{4 x ^{2} + 28 x + 49}{4}

= \frac{4 x ^{2} + 28 x + 49}{4}
