## ofree18 Group Title identify the solutions to the equation 3x^2-4x=-2 when you solve by using the quadratic formula 2 years ago 2 years ago

1. Mertsj Group Title

First add 2 to both sides so you can have the equation in the correct form.

2. Mertsj Group Title

Then you will see that a = 3, b = -4 and c = 2

3. Mertsj Group Title

Now plug those values into the quadratic formula.

4. ofree18 Group Title

which is?

5. Mertsj Group Title

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

6. ofree18 Group Title

the options look like this

7. ofree18 Group Title

|dw:1327793835199:dw|

8. BlingBlong Group Title

No real solutions to your probelm

9. BlingBlong Group Title

thus just write that unless your teacher specified that he wants you to answer in imaginary numbers

10. ofree18 Group Title

no it is one of those answers

11. ofree18 Group Title

yes it can be imaginary

12. myininaya Group Title

$x=\frac{-(-4) \pm \sqrt{(-4)^2-4(3)(2)}}{2(3)}$

13. myininaya Group Title

same thing as before simplify

14. ofree18 Group Title

what do i do with the squareroot of-8?

15. myininaya Group Title

$\sqrt{-8}=i \sqrt{8}= i \sqrt{4} \sqrt{2} =i (2) \sqrt{2}=2 i \sqrt{2}$
