First, let’s multiply and then simplify. Multiply. \displaystyle \frac {5 { {a}^ {2}}} {14}\cdot \frac {7} {10 { {a}^ {3}}} State the product in simplest form. Okay, that worked. But this time let’s simplify first, then ...
WebRational Expressions Examples Example 1: Find the length of a rectangular tabletop whose area is (x 2 + 4x - 5) sq units and breadth is (x - 1) units. Solution: Let the width be w = (x - 1) and the length be l. We know that the area of rectangle = l w. (x 2 + 4x - 5) = (x - 1) · l l = (x 2 + 4x - 5) / (x - 1) WebAug 24, 2024 · Example 9.7.1 Solve and write the solution in interval notation: x − 1 x + 3 ≥ 0 Solution Step 1. Write the inequality as one quotient on the left and zero on the right. Our inequality is in this form. x − 1 x + 3 ≥ 0 Step 2. Determine the critical points—the points where the rational expression will be zero or undefined.
