Answer 1

b^2 -4ac

Answer 2

sure try x^2 + x + 11

Answer 3

And an equation in this format: ax^2 + bx + c

Answer 4

or

2x^2 + x + 11 (1)^2 - 4*2+11 = -87

Answer 5

oops

(1)^2 - 4*2*11 = -87

Answer 6

How do you know that they will turn out negative? I have a hard time with these kind of questions all the time! Is there a trick or something?

Answer 7

Yeah, that's perfect! Thanks!

Answer 8

well I simply made each coefficient positive....

or you can have a and c negative...

then made the constant c a prime number...

and check that the coefficient b isn't the sum of the of c... and is small

Answer 9

Ohh okay. So i've just been over thinking it. I appreciate it dude (:
