A quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2)

You could use something called a carrot which is this symbol (^) in order to indicate an exponent if that is what you are looking for.

Does getting a degree mean you can be a detective

inessss [21]

It depends on what kind of degree you have. Being a detective needs training and special classes- you can get degrees for being a bet or a data analysts. It depends on what sort of degree you have.

OK. These problems are easy if you know the quadratic formula,
and they're impossible if you don't.

Here's the quadratic formula:

When the equation is in the form of Ax² + Bx + C = 0

then x = [ -B plus or minus √(B²-4AC) ] / 2A

I'm sure that formula is in your text or your study notes,
right before these questions. You should cut it out or
copy it, and tape it inside the cover of your notebook.
Then, you'll always have it when you need it, until
you have it memorized and can rattle it off.

The first question says 3x² + 5x + 2 = 0

Is this in the form of    Ax² + Bx + C = 0 ?

   Yes !       A=3 B=5   C=2

   so you can use the quadratic formula to solve it.

    x = [ -B plus or minus √(B²-4AC) ] / 2A

   = [ -5 plus or minus √(5² - 4·3·2) ] / 2·3

   = [ -5 plus or minus √(25 - 24) ] / 6

   = [ -5 plus or minus √1    ] / 6

   x =    -4 / 6 = -2/3
and
   x =    -6 / 6 = -1 .

The second question says

   4x² + 5x - 1 = 0

Is this in the form of Ax² + Bx + C = 0 ?

   Yes it is ! A=4 B=5 C= -1

   so you can use the quadratic formula to solve it.

    x = [ -B plus or minus √(B²-4AC) ] / 2A

Now, you take it from here.
