It can be written in the form y = ax2 + bx + c where a, b and c are constants and a â‰ 0

Think of it in reverse - trying to get it in the form of (x + a)2 This equals x2 + 2ax + a2 Compare the coefficients&constants to those of the original equation: x2 + 8x + c = x2 + 2ax + a2 2a = 8 and c = a2 a = 4, so c = 16

An equation is linear when it contains only variables of degree 1 and constants. ALL linear equations will be of the form: a1x1+a2x2+a3x3+...+anxn=c where an and c are constants.

A function is linear if it is of the form f(x) = mx + c where m and c are constants and a is not zero.The function implies that an increase of one unit in the input variable, x, always results in an increase of m units in the output.

If it can be written in the form y = mx + c where m and c are constants [or, equivalently, ax + by = k where a, b and k are constants] then y is a linear function of x.

Coding constants in c means writing the constants in a certain way that the c language understands.

A constant value cannot be changed once set. A variable can be changed whenever you want.

constants are values that does not chnage through out the program exceution..

I think you mean constants. A constant is a variable that can not have its value changed at run time eg. const int a = 100;

Enumerations are groups of named constants.

Suppose the variables are X and Y and the equation can be written in either of the following equivalent forms: bY = aX or aX - bY = 0 or Y/X = c where a, b and c are non-zero constants.

Some strings are constants, others aren't; some constants are strings, other aren't. So these are unrelated things. Examples: "text" -- constant string 123 -- constant number char s[40] -- variable string
