Apply the formula: $x+a+b\geq c$$=x+b\geq c-a$, where $a=5$, $b=-2x$, $c=0$ and $x=x^2$
$x^2-2x\geq 0-5$

$x^2-2x\geq 0-5$
Learn how to solve inégalités problems step by step online. Solve the inequality x^2-2x+5>=0. Apply the formula: x+a+b\geq c=x+b\geq c-a, where a=5, b=-2x, c=0 and x=x^2. Apply the formula: a+b=a+b, where a=0, b=-5 and a+b=0-5. Apply the formula: x^2+bx=x^2+bx+\left(\frac{b}{2}\right)^2-\left(\frac{b}{2}\right)^2, where b=-2, bx=-2x and x^2+bx=x^2-2x. Apply the formula: x^2+bx+f+g=\left(x+\sqrt{f}sign\left(b\right)\right)^2+g, where b=-2, bx=-2x, f=1, g=-1 and x^2+bx=x^2-2x+1-1.
