Calculate the discriminant Δ = b2 − 4ac = 22 − 4(2)(3) = 4 − 24 = − 20 < 0 so that the polynomial in the numerator is always positive.
WebApr 13, 2024 · These inequalities can give insight into the behavior of polynomials. For example, because x^2 + 2x + 1 = (x+1)^2 \ge 0, x2 +2x+1 = (x +1)2 ≥ 0, the minimum … WebWhen solving equations we try to find points, such as the ones marked "=0" But when solving inequalities we try to find interval (s), such as the ones marked ">0" or "<0" So this is what we do: find the "=0" points in between …
WebOct 6, 2024 · We begin by examining the solutions to the following inequality: x ≤ 3 The absolute value of a number represents the distance from the origin. Therefore, this equation describes all numbers whose distance from zero is less than or equal to 3. We can graph this solution set by shading all such numbers. Figure 2.6.6 WebUse Algebra to solve: A "root" is when y is zero: 2x+1 = 0. Subtract 1 from both sides: 2x = −1. Divide both sides by 2: x = −1/2. And that is the solution: x = −1/2. (You can also see this on the graph) We can also solve Quadratic Polynomials using basic algebra (read that page for an explanation). 2.
