Answer:
x = 4 or x = -3/2
Step-by-step explanation:
To simplify and solve this, let's use the quadratic formula.
So the format of a quadratic equation is supposed look like this:

Let's find a, b, c:
- a is the coefficient of x^2
- b is the coefficient of x
- c is the constant term
Now let's solve the equation.
Let's solve your equation step-by-step.
2x^2−5x−12=0
For this equation: a=2, b=-5, c=-12
2x^2+−5x+−12=0
Step 1: Use quadratic formula with a=2, b=-5, c=-12.

Answer:
Sean is wrong
Step-by-step explanation:
Slope tell the rate of the steepness of a line. Slope just telling you the rate, not the distance. You can't average the slope of two lines because the length of the line can be different.
Let's say A at (0, 0) and B (100, 200) and C at (101, 206). These coordinate fulfill the slope said above, but the slope of AC is 206/101= 2.04.
Sean can be right, but only if the horizontal length(x-axis distance) of AB=BC. If that so, using the example similar to above the coordinate can be A(0, 0), B(100, 200), C (200, 800). In this case, the slope is equal to the average of both lines.
