Question

I need to solve 2x^2 = 3x + 2. Can anyone show me how?

Answer 1

using the quadratic formula

Answer 2

2x^2 - 3x - 2 = 0

Answer 3

just plug it in to the formula then?

Answer 4

which part do you not understand?

Answer 5

I guess I don't know the formula or understand how to use it

Answer 6

for a quadratic equation in the form
\[ax^2+bx+c\]x is \[(-b±sqrt(b^2-4ac))/2a\]
You'll probably have two solutions, so use both the plus and the minus.

Answer 7

okay
\[x = \frac{-b \pm \sqrt{b^2 - 4*a*c}}{2a}\]
thats the formula
now you have
2x^2 - 3x - 2 = 0
ax^2 + bx + c = 0
plug in
make sense?

Answer 8

can I plug numbers into the equation?

Answer 9

into the quad. formula
