Question

Create a quadratic expression in standard form

Answer 1

Answer:

ax²+bx+c

ax²+bxy+cy²

Step-by-step explanation:

A quadratic expression is one where the maximum degree of the variable or variables ( in case of more than one variable the sum of the degree of the variables in a single term considered) is 2.

For example:  

A quadratic expression of a single variable is ax²+bx+c {Where a, b, and c are the arbitrary constants}

A quadratic expression with two variables is ax²+bxy+cy² {Where a, b, and c are the arbitrary constants}

And, a quadratic expression with three variables is ax² +by² +cz² +dxy +eyz +fzx {Where a, b, c, d, e, f are the arbitrary constants} (Answer)
