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

1. Mertsj

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

2. Mertsj

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

3. Mertsj

Now plug those values into the quadratic formula.

4. anonymous

which is?

5. Mertsj

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

6. anonymous

the options look like this

7. anonymous

|dw:1327793835199:dw|

8. anonymous

No real solutions to your probelm

9. anonymous

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

10. anonymous

no it is one of those answers

11. anonymous

yes it can be imaginary

12. myininaya

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

13. myininaya

same thing as before simplify

14. anonymous

what do i do with the squareroot of-8?

15. myininaya

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