Why semicolon? Tradition.What does it do? Terminates a single statement, eg:i+= 3; /* expression is a single statement */{ i= 3; --j; } /* no semicolon after the compound statement */
A quadratic expression is an expression which is written in the form ax2+bx+c, where a, b, and c represent constants, x represents a variable, and a is not equal to 0.
