Answer 1

Quadratic polynomials with zero discriminant.

Answer 2

and with rational roots.

Answer 3

or root, whatever you call it.

Answer 4

4x2 + 10x + 25

9x2 + 16x + 36

16x2 + 9x + 16

25x2 + 30x + 9
Which One?

Answer 5

To get the discriminant, use b^2-4ac

Answer 6

Which ever one equals 0 and has rational roots

Answer 7

which one is a perfect square
$$\bf(ax + b)(ax+b)$$

Answer 8

discriminant approach is easier, since you don't have to factor
