There are three zeros.
The discriminant is -27 and so there are no real roots.
You can approximate a square root as a decimal or fraction. If you want the exact number, you have to leave it with the square root sign.
If you calculate those square roots, you can count the integers in between pretty fast.
That really depends how the numbers are expressed - you have to learn separately how to calculate with decimals, with fractions, with expressions involving square roots, etc.

Almost any calculator can calculate square roots. Have the calculator calculate it. Then round the result to 1 decimal place.
The discriminant is -27 and so there are no real roots.
There are an infinite number of irrational numbers between 1 and 6. There are all the square roots from 1 to 36 except for 1, 4, 9, 16, 25, and 36. There are all the cube roots between 1 and 216 except for 1, 8, 27, 64, 125, 216. You can calculate fourth roots, fifth roots and continue calculating roots all year long. You should only have your supercomputer calculate irrational roots. Otherwise, you will duplicate. When you have calculated all roots of all prime numbers that fall between one and six, and added in all physical constants, then you will know the answer.
Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.
Relax. You'll never be asked to do that. Only numbers have square roots. Triangles don't.

The approx difference is 0.7
READ values of a, b and c,if a is zero then stop as we do not have a quadratic,calculate value of discriminantif D is zero then there is one root: ,if D is > 0 then there are two real roots: and ,if D is < 0 there are two complex roots: and ,PRINT solution.
Most square roots, cube roots, etc. - including this one - are irrational numbers. That means you can't write them exactly as a fraction. Of course, you can calculate the cubic root with a calculator or with Excel, then find a fraction that is fairly close to it.
