Find the Perfect Square Trinomial x^2-2.2x+c

$x^{2} - 2.2 x + c$

Step 1

Move $- 2.2 x$ .

$x^{2} + c - 2.2 x$

Step 2

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

Divide $2.2$ by $2$ .

${(- 1 \cdot 1.1)}^{2}$

Multiply $- 1$ by $1.1$ .

${(- 1.1)}^{2}$

Raise $- 1.1$ to the power of $2$ .

$1.21$
