What is the solution set of the quadratic inequality x^2+x-2>0?

One later education question and answer asked students to state what they believe is the main important point for a student to do in order for you to score success. From the numerous answers, one which that stood out was practice. Successful people commonly not born successful; they become successful from hard work and dedication. If you wish to get your goals, keep this in mind! down below are one of the answer and question example that you could simply utilise to practice and boost your understanding and also give you insights that would guide you to sustain your study in school.

Question:

What is the solution set of the quadratic inequality x^2+x-2>0?

Answer:

Answer: The solution set is

Step-by-step explanation:  We are given to find the solution set of the following quadratic inequality:

The solution is as follows:

We know that if ‘a’ and ‘b’ are two numbers such that a × b > 0, then either both ‘a’ and ‘b’ are greater than 0 or both of them are less than 0.

Therefore, we have

either

or

Thus, the required solution set is x < -2 and x > 1. We can also write the solution set in terms of intervals as

They would possibly hopefully assist the student sort out the question by obtaining the questions and answer examples. You will possibly then have a discussion with your classmate and continue the school learning by studying the topic as a group.
