Apply the formula: $x^2+bx+c$$=x^2+bx+c+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2$, where $b=10$ and $c=10$
$x^2+10x+10+\left(\frac{10}{2}\right)^2- \left(\frac{10}{2}\right)^2$

$x^2+10x+10+\left(\frac{10}{2}\right)^2- \left(\frac{10}{2}\right)^2$
Learn how to solve factorisation polynomiale problems step by step online. x^2+10x+10. 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=10 and c=10. Apply the formula: \frac{a}{b}=\frac{a}{b}, where a=10, b=2 and a/b=\frac{10}{2}. Apply the formula: \frac{a}{b}=\frac{a}{b}, where a=10, b=2 and a/b=\frac{10}{2}. Apply the formula: a^b=a^b, where a=5, b=2 and a^b=5^2.
