Apply the formula: $x^2+bx+c$$=x^2+bx+c+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2$, where $b=8$ and $c=-15$
$x^2+8x-15+\left(\frac{8}{2}\right)^2- \left(\frac{8}{2}\right)^2$

$x^2+8x-15+\left(\frac{8}{2}\right)^2- \left(\frac{8}{2}\right)^2$
Learn how to solve factorisation polynomiale problems step by step online. x^2+8x+-15. 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=8 and c=-15. Apply the formula: \frac{a}{b}=\frac{a}{b}, where a=8, b=2 and a/b=\frac{8}{2}. Apply the formula: \frac{a}{b}=\frac{a}{b}, where a=8, b=2 and a/b=\frac{8}{2}. Apply the formula: a^b=a^b, where a=4, b=2 and a^b=4^2.
