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)

Answers:
- A in the upper left
- D in the upper right
- B in the lower left
- C in the lower right
==================================================
Explanation:
Segments AB and AD have the letter A in common. This must mean they intersect at point A; i.e. they both have point A on their segment. Therefore, point A is in the upper left corner.
This logic is used to determine the other three corner points as well. The upper right corner is point D since AD and DC have D in common. The same goes for the bottom points as well.
If the second leg is x so
x² = b² - a²
x² = (20)² - (12)² = 256
x = 16 in
