As a fraction in simplified form, 3.5 is equal to 7/2 .

But you say you want something that's repeating.

That's a problem . . . there's no part of 3.5 that's repeating now, and if I just go ahead and write something that does repeat, my invention will change the value, and it won't be equal to 3.5 any more.

Here's one possibility, I guess: 3.500 000 000 000 000 000 000 . . .

The zeros repeat infinitely, and no matter how many (or how few) zeros you write, the value of the number is always 3.5 and it never changes.

If it's the ' 5 ' on the end that you want to see repeating, that's actually easier to work with. Then we have 3.555 555 555 555 555 555 . . .

THOSE fives really do keep repeating and never end, and that number is equal to (3 and 5/9) or (32/9) .

Answer:

Step-by-step explanation:

a = 3

b = 3

c = 1

Discriminate = sqrt(b^2 - 4ac)

Discriminate = sqrt(9 - 4*3*1)

Discriminate = sqrt(9 - 12)

Discriminate = sqrt(-3)

What negative value means that there are no real roots and the y intercept = 1. You should always graph this kind of question, which I am doing for you. I use Desmos which is a very handy program.

You should notice that the minimum is above the x axis. That means there are no real roots, just as the discriminate tells you.
