This is the generalized trinomial equation (aka quadratic):
y = ax2 - bx - c
Before factoring, always check the discriminant of the quadratic equation, which is:
b2 - 4ac
If it is a rational square (16, 25, 196, 225), then it is factorable. If it is not, then it is not factorable.
In this case, it is not, since the discriminant is equal to 2√3.
Now, you will have to use the quadratic formula:
(-b2 +/- √(b2 - 4ac))/2
This will give you (14 +/- 2√3)/2

Show whether 0 3 is the solution of the linear system below 2x plus y equals -3 x plus 2y equals 8?
For (x, y) = (0, 3) the first equation gives: 2*0 + 3 = -3 that is, +3 = -3 which is FALSE. So (0, 3) is not a solution.

What is the country code for Sweden when calling from Australia?

How do you factor 0 equals 2m squared minus 2m plus 36?
0 = 2m^2 - 2m + 36 0 = 2(m^2 - m + 18) 0 = m^2 - m + 18
