There is no rational solution.
3x2-24x-48 is not factorable.
The expression is not factorable with rational numbers.
yes it is
There is not enough information to answer this accurately.
Yes.
Yes.
If the quadratic is written in the form ax2 + bx + c (where a not 0) then for it to be factorable, b2 - 4ac (the discriminant) must be a perfect square.
Not factorable
4x2 - 9y Not factorable from what I see.
(7y-12)(7y+12)
If after finding all the factors of the product of the highest term's coefficient and the linear term, none of the can add or subtract to give the middle term then it is not factorable. x^2 +5x+6 is factorable. 1x6; 2x3 2+3=5 so it can be factored. x^2+7x+6 is factorable but x^2+8x+6 is NOT factorable because 1 and 6 as well as 2 and 3 can't add up to the middle term.
