How to solve an inequality algebra

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. Example: Alex has more money than Billy, and so Alex is ahead. WebAug 13, 2024 · Solve x2 − 6x + 8 < 0 graphically. Write the solution in interval notation. Solution: Step 1: Write the quadratic inequality in standard form. The inequality is in standard form. x2 − 6x + 8 < 0. Step 2: Graph the function f(x) = ax2 + bx + c using properties or transformations. We will graph using the properties.

WebTake the solution (s) and put them in the original equation to see if they really work. Example: solve for x: 2x x − 3 + 3 = 6 x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3 (x−3) = 6 Bring the 6 to the left: 2x + 3 (x−3) − 6 = 0 Expand and solve: 2x + 3x − 9 − 6 = 0 5x − 15 = 0 5 (x − 3) = 0 WebWhen solving inequalities, it is usually easiest to collect the variables on the side where the coefficient of the variable is largest.
