Use the quadratic formula to solve for x. 2x^2+7x-6=0

OpenStudy (anonymous):

\[x=-7\pm \sqrt{49+48}/4\]

OpenStudy (turingtest):

myko is applying the formula for any equation in the form\[ax^2+bx+c=0\]called the "quadratic formula, which is\[x={-b\pm\sqrt{b^2-4ac}\over2a}\]

OpenStudy (anonymous):

TuringTest could you show me the correct way to solve for x?

OpenStudy (turingtest):

that formula is all there is too it brb

OpenStudy (turingtest):

the correct way to solve for x is to just identify a, b, and c and plug that into the quadratic formula

OpenStudy (turingtest):

sctatch that, there is another way by factoring

OpenStudy (turingtest):

scratch that*

OpenStudy (turingtest):

ask yourself "what two numbers, a and b, can be multiplied to give -6 and add to give 7 ?"

OpenStudy (turingtest):

the quadratic formula always works for equations of the form\[ax^2+bx+c=0\]but learning to recognize when something can be factored is a better way to develop skill in math

I want to ask you if my answer is right but I tried right it out through this and I don't know how..): I honestly tried it and was wondering if you could share what you got so I can see if I did it right, please.
