There's no solution to [ 2x2 - 13x - 20 ], because it's not an equation, it doesn't make
any statement, and it doesn't ask any question.
If you said that it's equal to something, then we'd have to find what value of 'x' makes
it a true statement. But right now, it's not even a statement. It's just an expression.
It stands for a number, the number depends on the value of 'x', and it changes every
time 'x' changes.

Does the solution is the empty set mean there is no solution?
Yes, empty set means null which is no solution.
What is empty set in algebra?
An empty set is a set with no elements. It can be symbolized by {} or ø. The solution set for an equation that has no solution is also called an empty set.
What do you call a set with no solution?
A set would not normally have a solution. An equation or an inequality might.
How big is the solution set for an equation that cannot be solved?
Unsolvable equations have no solutions so the solution set would be [ ]. (empty set)
What is the whole number in the solution set for 9x plus 2x plus 26?
9x + 2x + 26 is an expression, not an equation (or inequality). It therefore cannot have a solution so that its solution set is the null set. There is nothing in the solution set - no integers, rationals, irrationals: nothing!
