How to solve an inequality algebra
WebSolve the inequality for a a + b > c We subtract b from both sides: a + b − b > c − b a > c − b If we multiply or divide by a negative number than we must reverse the order of the inequality If c is positive (and not zero) and a < b, then ac < bc and a/c < b/c If c is negative (and not zero) and a < b, then ac > bc and a/c > b/c Video lesson

Rearrange the inequality by dividing … WebStep by step guide to solve one-step inequalities. Similar to equations, first isolate the variable by using the inverse operation. For dividing or multiplying both sides by negative numbers, flip the direction of the inequality sign. One–Step Inequalities.
WebOct 6, 2024 · In general, given any algebraic expression X and any positive number p: If X ≤ p then − p ≤ X ≤ p. This theorem holds true for strict inequalities as well. In other words, we can convert any absolute value inequality involving " less than " into a compound inequality which can be solved as usual. Example 2.6.7: 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.
