The discriminant. b^2-4ac must be >0 for real number factors.

It's [b ^{2}-4ac\] But I don't remember why or how. To solve it it's easy, think of your equation in this way: a is paired with x because x is earlier in the alphabet, so is a b is paired with y because y is after x in the alphabet, as is b to a and c is always your number on it's own.

Don't you have the quadratic formula?

  • anonymous
You can also do it by grouping

  • anonymous
You just have to plug the numbers from the equation they gave you into the answer you chose for the first part and solve it.

  • anonymous
Actualy, grouping is not going to work here. Use the quadratic formula

if i seen it i would understand

The whole quadratic formula isn't needed, just the part of the equation picked in part 1. Take the b^2 - 4ac and put in the values of b, a, and c and compute it using a calculator.

Oh yes, only the discriminant is needed. Skimmed that part.

The second part of the question is asking you to find b^2 - 4ac So you need to find a,b, and c, and use the above formula the a, b, and c come from a x^2 + bx + c so match your quadratic 2x^2 + 7x + 3 = 0 to find a,b, and c.
