Apply the formula: $x^2+bx+c$$=x^2+bx+c+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2$, where $b=18$ and $c=9$
$x^2+18x+9+\left(\frac{18}{2}\right)^2- \left(\frac{18}{2}\right)^2$

$x^2+18x+9+\left(\frac{18}{2}\right)^2- \left(\frac{18}{2}\right)^2$
Learn how to solve factorisation polynomiale problems step by step online. x^2+18x+9. Apply the formula: x^2+bx+c=x^2+bx+c+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, where b=18 and c=9. Apply the formula: \frac{a}{b}=\frac{a}{b}, where a=18, b=2 and a/b=\frac{18}{2}. Apply the formula: \frac{a}{b}=\frac{a}{b}, where a=18, b=2 and a/b=\frac{18}{2}. Apply the formula: a^b=a^b, where a=9, b=2 and a^b=9^2.
