WebMore Formal. More formally we have: Which says the absolute value of x equals: x when x is greater than zero; 0 when x equals 0; −x when x is less than zero (this "flips" the number back to positive); So when a number is positive or zero we leave it alone, when it is negative we change it to positive using −x. WebWhether the discriminant is greater than zero, equal to zero or less than zero can be used to determine if a quadratic equation has no real roots, real and equal roots or real and unequal roots.

WebAug 24, 2024 · The critical point $x=1$ makes the whole rational expression 0. The inequality requires that the rational expression be greater than or equal to. So, 1 is part of the solution and we will mark it with a bracket. Recall that when we have a solution made up of more than one interval we use the union symbol, $\cup $, to connect the two intervals.

WebAs we just saw, putting minuses in front of a and b changes the direction of the inequality. This is called the "Additive Inverse": If a < b then −a > −b. If a > b then −a < −b. This is really the same as multiplying by (-1), and that is why it changes direction.
