Apply the formula: $x+a+b\geq c$$=x+b\geq c-a$, where $a=8$, $b=-6x$, $c=0$ and $x=x^2$
$x^2-6x\geq 0-8$

$x^2-6x\geq 0-8$
Learn how to solve calcolo differenziale problems step by step online. Solve the inequality x^2-6x+8>=0. Apply the formula: x+a+b\geq c=x+b\geq c-a, where a=8, b=-6x, c=0 and x=x^2. Apply the formula: a+b=a+b, where a=0, b=-8 and a+b=0-8. Apply the formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, where b=-6, bx=-6x and x^2+bx=x^2-6x. Apply the formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, where b=-6, bx=-6x, f=9, g=-9 and x^2+bx=x^2-6x+9-9.
