Find the Perfect Square Trinomial x^2-3/4x

$x^{2} - \frac{3}{4} x$

Simplify each term.

Combine $x$ and $\frac{3}{4}$ .

$x^{2} - \frac{x \cdot 3}{4}$

Move $3$ to the left of $x$ .

$x^{2} - \frac{3 x}{4}$

To find the $c$ value $c = {(\frac{b}{2})}^{2}$ , divide the coefficient of $x$ by $2$ and square the result.

Multiply the numerator by the reciprocal of the denominator.

${(- \frac{3}{4} \cdot \frac{1}{2})}^{2}$

Multiply $- \frac{3}{4} \cdot \frac{1}{2}$ .

Multiply $\frac{1}{2}$ by $\frac{3}{4}$ .

${(- \frac{3}{2 \cdot 4})}^{2}$

Multiply $2$ by $4$ .

${(- \frac{3}{8})}^{2}$

Use the power rule ${(a b)}^{n} = a^{n} b^{n}$ to distribute the exponent.

Apply the product rule to $- \frac{3}{8}$ .

${(- 1)}^{2} {(\frac{3}{8})}^{2}$

Apply the product rule to $\frac{3}{8}$ .

${(- 1)}^{2} \frac{3^{2}}{8^{2}}$

Raise $- 1$ to the power of $2$ .

$1 \frac{3^{2}}{8^{2}}$

Multiply $\frac{3^{2}}{8^{2}}$ by $1$ .

$\frac{3^{2}}{8^{2}}$

Raise $3$ to the power of $2$ .

$\frac{9}{8^{2}}$

Raise $8$ to the power of $2$ .

$\frac{9}{64}$

Add $\frac{9}{64}$ to get the perfect square trinomial.

$x^{2} - \frac{3}{4} x + \frac{9}{64}$
