What is a complex sentence?

A complex sentence is a sentence that has one main clause and at least one subordinate or dependent clause.

A compound sentence is a sentence that has two or more main clauses.

A subordinate clause in a complex sentence is a clause that does not express the main idea of the entire sentence but rather expresses an idea that clarifies or provides additional information about the main clause.

Some examples of complex sentences are:

1) I went to school with my friend, who was eager to take the test.

2) I did not have to wait for the bus because my friend brought his car.

Some examples of compound sentences are:

1) I went to school with my friend; however, he was not eager to take the test.

2) I called my friend today, but he did not answer the phone.

What is a subordinate clause?

A subordinate clause is a dependent clause, or a clause that cannot stand on its own as a sentence. It can be either a noun clause or an adverbial phrase.
There are two types of clauses: main and subordinate. The difference between the two is that the main clauses can stand alone as a sentence, whereas the subordinate clause cannot.
The subordinate clauses are often found at the beginning of sentences, and they usually function to modify nouns or verbs in the main clause.
An example of a subordinate clause is "when I am done with my homework", which cannot be used as a complete sentence. However, it can be used as a part of a bigger sentence, for example, “When I am done with my homework, I will watch my favourite TV show.” https://www.notesflux.com/2016/10/clauses.html
