What is the value of

Question

alones · Answer

$$10x^2+20x+8=0 $$

alones · Answer

I'm not sure tbh.
$$\sqrt{20-4(10)(8)}$$

anonymous · Answer

for discriminant the 20 need square it there inside squarroote

agent0smith · Answer

Didn't you a big ol' quadratic formula thread yesterday with @johnweldon1993? refer to that.

alones · Answer

Aaaah that post @agent0smith why did u bring it up :3
plus tagging him

agent0smith · Answer

Tagged him cos he'd be disappointed if you took away nothing from it ;)

alones · Answer

Ayeee dudee

agent0smith · Answer

The formula and steps you need are in that question

alones · Answer

OKay,okay sothe formula is $$\sqrt{b^2-4ac}$$
So i did that lready and
a=10^2
b=20
c=8
and than i get lost >.>

agent0smith · Answer

That is NOT the quadratic formula. That is the discriminant. 

What does this question ask you to find?

alones · Answer

Ugh *facepalm*
What is the value of $$b^2-4ac$$c for the following equation?
$$10x^2+20x+8=0 $$

agent0smith · Answer

Then that's kinda important to know.

So what are a b and c?

Then just plug them into $$\Large b^2-4ac$$

alones · Answer

I DID

alones · Answer

A=10
b=20
c=8
$$\sqrt{(20)-4(10)(8)}$$

agent0smith · Answer

Yes, correct for a, b, c.

You aren't asked for that. The question asked for $$\Large b^2-4ac$$

alones · Answer

Ugh how than?

agent0smith · Answer

Plug in a=10, b=20, c=8 into this $$\huge  b^2-4ac$$

alones · Answer

Ooooh so now sqare toot?
$$ 20^{2}-4(10)(8)$$

alones · Answer

I FIANLLY GOT 80!

agent0smith · Answer

It does not ask for a square root. Based on the question you gave.

alones · Answer

Yeah it doesn't.TANKS AGENT0
