Step 1: Cancel 4/6 and change to 2/3.
Step 2: Adjust Fractions based on the LCM.
The LCM of 3 , 9 : 9
Step 3: Subtract the numbers : - 6 -7 = -13
Area of ABC : AB*AC/2
the maximum of the parabola is reached at x=-4/(2*(-1))=2 hence A is at (2,0) and B is at (2,(-2)^2+4*2+C)=(2,12+C)
C is the second root (x-intersect), which we can find :
determinant1 : D=16-4*(-1)*C=4(4+C) thus the second root is at x=
Hence the area of the triangle is
hence 
.
We remark that
Hence 4+C=16 thus C=12
