A quadratic equation in standard form is written ax2 + bx + c = 0, where a, b, and c are real numbers and a is not zero.





A. True


B. False

A quadratic equation in standard form is written ax2 + bx + c = 0, where a, b, and c are real numbers and a is
I would say true. If a was zero you wouldn't have a true quadratice equation!
Reply:The answer is A





Why a should not be zero is if a is zero then the equation no longer remains an equation of degree 2. it reduces to a linear equation
Reply:my gut instinct is that it's true, but i'm not sure if a, b, %26amp; c have to be real numbers.

Reply:a, b, c, and x need not be real numbers and this is still a polynomial of degree 2 ("quadratic").





a can't be zero; if it were, you would have bx+c which is a 1st degree polynomial ("linear"), not a quadratic.
Reply:A. True [assuming that your "x2" in your equation is meant as a "2" exponent ]





i.e. ax2 + bx + c = 0 means





ax² + bx + c = 0

a %26amp; c not = 0
