Question 113620
Integers: {{{2x^2+5x-3}}} Simply use whole numbers for the coefficients


Rational numbers: {{{(1/2)x^2+(3/4)x-(1/3)}}} Use fractions for the coefficients


Irrational numbers: {{{sqrt(2)x^2+sqrt(7)x-sqrt(5)}}} Use square roots (there are many more forms, but we'll just use these) as the coefficients
