Question

Can someone please help me? I need to know the answer to this (simplified answer).
Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

−b b2 − 4ac 2a

Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation:

2x2 + 7x + 3 = 0

Answer 1

i think it is b2-4ac

Answer 2

I am prett sure that is the answer to the first part but you are suppose to use that to find its value given the following quadratic equation:

2x2 + 7x + 3 = 0

Answer 3

And that is what I don't know the answer to? Can you help?

Answer 4

if you want to find the value of x,
\[x = \frac{ -b \pm \sqrt{b ^{2}- 4ac} }{ 2a }\]
a= coefficient of the x^2 term
b=coefficient of the x term
c=constant
