Solve 3x2 + 4x = 2.

OpenStudy (anonymous):

I will fan and medal

OpenStudy (anonymous):

Is the 3x squared? is it 3x^2+4x=2

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Does it tell you how it wants it solved? Like a specific way?

OpenStudy (anonymous):

the quadratic formula

OpenStudy (anonymous):

do you know the formula by heart?

OpenStudy (anonymous):

x=-b+/- sqrt b^2 -4(a)(c) all over 2(a)

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Ok so first you need to set your equation equal to zero

OpenStudy (anonymous):

3x2+4x-2=0

OpenStudy (anonymous):

good. Now do you know your values for a, b, and c?

OpenStudy (anonymous):

Plug them into the equation?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

(-3 \[\pm \sqrt{16 +24}) / 6\]

OpenStudy (anonymous):

the two lines are in continuation

OpenStudy (anonymous):

It should look like x=-4\[\pm \sqrt{4^2-4(3)(-2)}\] over 2(3)

OpenStudy (anonymous):

So would it be -2 plus radical 10 all over 3|dw:1434907050388:dw|

OpenStudy (anonymous):

How did you get that?

OpenStudy (anonymous):

\[-4+\sqrt{}\]40

OpenStudy (anonymous):

\[x=-4\pm \sqrt{16+24} \over 6\]
