Question 171526
You need to write three equations of the form {{{ax^2+bx+c=0}}}


Integers are whole numbers, either positive or negative.  -4, 5, and 23 are integers, for example.  0 (zero) is also an integer.


Rational numbers are numbers that can be expressed as the quotient of two integers.  {{{-3/4}}}, {{{1/2}}}, and {{{37/14}}} are rational numbers  (all integers are also rational, by the way)


Irrational numbers are any real numbers that CANNOT be expressed as the quotient of two integers.  {{{sqrt(2)}}}, {{{-sqrt(87)}}}, {{{pi}}}, and {{{e}}} (the base of the natural logarithms) are irrational numbers.


In each case, pick any numbers you like within the given constraints for the caracter of the coefficients, and substitute them for a, b, and c in {{{ax^2+bx+c=0}}}
