Answer:
Step-by-step explanation:
The quadratic formula is as follows:
It is used for factoring second degree polynomials ONLY!!! That's why it's called the quadratic formula...quadratics are second degree polynomials. The a, b and c are found in the standard form of a quadratic equation:
Just plug them into the formula, but be careful with the "-4ac". Sometimes that mistakenly leads to an unwanted negative sign under you radical. Unless you are dealing with imaginary numbers, your solutions should be real.

An irrational number is a number that can't be written as a simple fraction while a rational number is a number that can be written as the ratio of two integers, that is, as a simple fraction. So in this case we have the number 2 which is ration, and we can multiply it by an irrational number such that the product is an irrational number. So any irrational number will meet our requirement because the product of any rational number and an irrational number will lead to an irrational number. For instance:
