Answer:

x² + 2x - 4

Step-by-step explanation:

The quadratic equation is ax² + bx + c =0

To solve this, you plug it into the quadratic formula (-b±√(b²-4ac))/(2a).

As it shows in the picture, -B = 2. There is no negative on the two in the equation because the quadratic formula makes any positive number negative in the first part.

The values of A and C are give in the parenthesis because they are being multiplied by -4.

The value for A = 1 and we can leave that as x² because 1 and x have the same value.

The value for C = -4 and that goes at the back of the equation, turning the plus sign after 2x negative.

When you put the equation together, you get x² + 2x - 4
