Exercise

$\left(x-5\right)\left(x+4\right)\ge0$

Step-by-step Solution

Learn how to solve trigonometric equations problems step by step online. Solve the inequality (x-5)(x+4)>=0. Multiply the single term x+4 by each term of the polynomial \left(x-5\right). Multiply the single term x by each term of the polynomial \left(x+4\right). When multiplying two powers that have the same base (x), you can add the exponents. Multiply the single term -5 by each term of the polynomial \left(x+4\right).
