the correct answer is going to be 54
36 + 90 = 126
180 - 126 = 54
x = 54
The quadratic function when graphed out should look like either a 'U' or an 'n' (parabola). Quadratic functions have formulas which are typically in the form of: A(x^2)+Bx+C where A, B, C are numbers and if you plot them then as mentioned before you should get a parabola.
If my math is correct is should be 2 and 2/5. sorry if that's wrong
The answer is B&D as you said
