Question

What is C in x^2 + x = 12

Answer 1

-12. put it in standard form and set it equal to 0

Answer 2

yeah, what's C supposed to stand for?

Answer 3

take note of the general form of a quadratic equation.
\[ax^2 + bx + C = 0\]
in your case it is
\[x ^2+x=\]
so you have to make it
\[x^2+x-12 = 0\]
btw, c refers to constant term

Answer 4

correction on the second equation
\[x^2+x = 12\]

Answer 5

x^2 + x -12=0
standard from is ax^2 + bx + c = 0
a b and c are constants (the opposite of a variable) that are actual numbers.
x^2 is like writing 1x^2 and that 1 is what a would be.

Answer 6

well what if I do -x^2 - x + 12 = 0? now C = 12.

Answer 7

well in reality, we make the leading coefficient as positive. that why we have to make it x^2+x-12=0
