Start with the number 2.

And continue with that pattern from there.
X^2 + X - 12 = 0
(X + 4)(X - 3) = 0
X = -4 and X = 3.
The answer to the mathematics question presented above is 'True'. It is correct to say that in (r theta), the value of r can be negative. A negative radius can be used when it comes to graphing a "polar'' function. Thus, the answer to the question is 'true'.
