Are irrational numbers rational numbers

No, rational numbers and not irrational numbers. In other words, they are similar.

Step-by-step explanation:

Rational numbers are numbers that can be represented as a quotient.

For example:

-5/3, 7/9, 0.5, and 4/1

Irrational numbers are numbers that can not be written as a quotient.

Numbers such as

\sqrt{3} , -\sqrt{7}, \pi

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

so, converting firstly the mixed fractions to improper fractions and then "adding".
