3x^2=2x=2x+7

OpenStudy (anonymous):

too many equal signs

OpenStudy (misty1212):

HI!!

OpenStudy (misty1212):

is it \[3x^2-2x=2x+7\]?

OpenStudy (anonymous):

3x2 - 2x = 2x + 7 ⇒ x=2.333 , x=-1 am I right

OpenStudy (anonymous):

no

OpenStudy (anonymous):

wat did I do wrong

OpenStudy (anonymous):

\[\frac{7}{3}\neq 2.333\]

OpenStudy (anonymous):

@misty1212 the problem is 3x^2-2x=2x+7

OpenStudy (misty1212):

subtract \(2x+7\) from both sides to set it equal to zero, and solve\[3x^2-4x-7=0\] by factoring

OpenStudy (misty1212):

i am bad at factoring, but i think it factors as \[(3x-7)(x+1)=0\]

OpenStudy (misty1212):

as a matter of fact, i am sure it does

OpenStudy (anonymous):

yes the answers are right because my teacher gives us the answers but we have to show the work and she doesn't really teach us so i never know who to do the homework

OpenStudy (misty1212):

are you asking how to factor it?

OpenStudy (wolf1728):

Were you taught to use the quadratic formula?

OpenStudy (misty1212):

or how to solve ? once you have \[(3x-7)(x+1)=0\] set each factor equal to zero and solve for \(x\) so \[x+1=0\\ x=-1\] and \[3x-7=0\\ 3x=7\\ x=\frac{7}{3}\]

OpenStudy (anonymous):

thats what i did and i got the answers right

So, everything's okay Cheyenne?
