step by step plzz

OpenStudy (anonymous):

3x^2+4x+3=0 3x^2+4x=0-3 3x^2+4x=-3

OpenStudy (saifoo.khan):

can't be.

Simply is a wingspan word for someone who doesn't understand.

OpenStudy (eyust707):

do you know what the quadratic is?

OpenStudy (anonymous):

it is 2

OpenStudy (anonymous):

${-b \pm \sqrt{b ^{2}-4ac}}/{2a}$

OpenStudy (eyust707):

yeah!

OpenStudy (anonymous):

it algebra

OpenStudy (saifoo.khan):

$\frac{-b \pm \sqrt{b ^{2}-4ac}}{2a}$

OpenStudy (eyust707):

ok and the function is in the form.. ax^2 + bx +c =0

OpenStudy (anonymous):

how'd you get the division line?

OpenStudy (anonymous):

yeep

OpenStudy (eyust707):

so what does a = ? b=? and c =?

OpenStudy (eyust707):

*he probably used parenthesis* i knew what you meant tho

hero (hero):

No real solutions

OpenStudy (eyust707):

hero, how does that help math dude?

OpenStudy (zarkon):

$\text{if you do a google search for }\LaTeX\text{ you will find all the commands you desire.}$

hero (hero):

It helps

3x^2+4x+3=0 Solve the quadratic equation by completing the square: Divide both sides by 3: x^2+(4 x)/3+1 = 0 Subtract 1 from both sides: x^2+(4 x)/3 = -1 Add 4/9 to both sides: x^2+(4 x)/3+4/9 = -5/9 Factor the left hand side: (x+2/3)^2 = -5/9 Take the square root of both sides: sqrt(x+2/3) = (i sqrt(5))/3 Eliminate the absolute value: x+2/3 = -(i sqrt(5))/3 or x+2/3 = (i sqrt(5))/3 Subtract 2/3 from both sides: x = -1/3 i (-2 i+sqrt(5)) or x+2/3 = (i sqrt(5))/3 Subtract 2/3 from both sides: x = -1/3 i (-2 i+sqrt(5)) or x = 1/3 i (2 i+sqrt(5))

hero (hero):

Copied and pasted from somwhere

OpenStudy (eyust707):

haha y u gotta hate?

hero (hero):

It's not hate if it's the truth

hero (hero):

Truth doesn't hate

OpenStudy (anonymous):

@hero : i am just helping him yaar!!!!!

hero (hero):

lol

OpenStudy (eyust707):

lol

hero (hero):

I'm lucky I'm not in the same room with her. My head would be gone by now.

OpenStudy (anonymous):

lol

OpenStudy (eyust707):

hahahah

OpenStudy (anonymous):

oh come on what are you trying to say hero!!!

OpenStudy (eyust707):

hmmmmmm
