Find the Perfect Square Trinomial x^2-1.6x+c

$x^{2} - 1.6 x + c$

Step 1

Move $- 1.6 x$ .

$x^{2} + c - 1.6 x$

Step 2

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

Divide $1.6$ by $2$ .

${(- 1 \cdot 0.8)}^{2}$

Multiply $- 1$ by $0.8$ .

${(- 0.8)}^{2}$

Raise $- 0.8$ to the power of $2$ .

$0.64$
