Answer:
This equation has no real roots
Step-by-step explanation:
We want to solve
We group all terms on the left:
Divide through by -6
The discriminant is
This means the given equation has no real solution, since the discriminant is less than 0

Triangles ABX and CDX are similar triangles. So the ratio of lengths between corresponding legs of the triangles will have the same value. You know that they're similar triangles because both of them are right triangles (so you know that one angle is the same in both) and that arc draw on both angles AXB and CXD indicate that those angles match as well. That tells you there's a second angle that's matching in both triangles, and because two of the angles match, you also know that the unmarked angle matches as well since all the angles in a triangle have to add up to 180 degrees.
So you know that AB/CD = BX/DX. Substitute known values and you get
AB/CD = BX/DX
12/CD = 2.5/5
Now solve for CD
12/CD = 2.5/5
12/CD = 1/2
24/CD = 1
24 = 1 * CD
24 = CD
So the value of CD is 24.</span>
From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
