Help !!

Answer 1

I'm on it!

Answer 2

b2-4ac if it gives you one solution, you can factor

Answer 3

I attached it ^.^

Answer 4

Can you take the square root of a negative number?

Answer 5

Yes ?

Answer 6

Can you take the square root of a negative number?

True, it is yes, BUT you get an imaginary number, which means you can not factor the quadratic into two real factors.

Answer 7

b^2-4ac is called the discriminant
See http://en.wikipedia.org/wiki/Discriminant

Answer 8

In the equation , the discriminant is

Answer 9

I see but I'm having trouble factoring it.

Answer 10

The answe should be 1,7 ? @phi

Answer 11

a= 2, b=7 , c=3

you want b^2 -4ac

Answer 12

The question asks you to pick the expression that tells you if you factor the quadratic
that means pick the discriminant (i.e. b*b-4*a*c)
and then figure out its value for the quadratic they give you.

Answer 13

Can you find the value of b*b-4*a*c
if a=2, b=7, c=3 ?
