bery good? are you being funny?
I presentiment katy will become bery good in Maths.
Not stupid. You just need practice. Math isn't hard. It just takes some getting used to.
lol...of course you all are....I am the stupid one..hehehe
Nah we just pretend to be.
thanks a lot guys...i get them now...you all are smart.
2 real roots when the discriminant is positve. 2 imaginary roots when the discriminant is negative. Two equal roots when the discriminant is zero.
For the 1b problem.
thanks a lot guys....
Of course, but I thought that you are not permissed to calculate the discriminant.
For 2) it doesn't ask you to find the values of x, just the discriminant.
In this case, the discriminant would be 3² - 4*2*(-10) = 89.
Because it is positive, this shows that both roots will be real and distinct.
That was joke
I'm just guessing...
