Question

Evaluate the discriminant for each equation. Then use it to determine the number and type of solutions. 8x² = -2x -6

Accepted Answer

Identify the number and type of solutions for the given quadratic equation by calculating is discriminate or X squared is equals to five X negative five X minus 11. To calculate this, we first want this in the standard form of a quadratic A X squared plus B X plus C. So we will, we move everything over to one side. Let's move our forex squared over 24 x squared. You will get zero as equals to negative four X squared minus five X minus 11. Now, a discriminate formula is given by B squared minus four AC, we will check the sign or discriminate afterwards to determine what type of solutions for. Now, we will plug in our values into this equation. We have ACC seven R B is negative five. So we have negative five squared minus four multiplied by our A negative four and by our C negative 11, We can get 25 minus, Let's see, four times 9 - four. That the end of 11 that gives us 1 76, 25 -1 76 gives us -151. Uh because this discriminate is a negative value, we can then determine we have two non-real solutions. We can then say the answer to our problem will be answers. C OK. I hope to help you solve the problem. Thanks for watching. Goodbye.
