Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring. -b b2 - 4ac 2a use the part of the quadratic formula that you choose above and find its value given the quadratic equation: 2x2 + 7x + 3 = 0

Recall the quadratic formula is 



and the tell-tale part is the discriminant, namely the radicand above,



so, we can check its discriminant, and if it's negative, then we know it has no solutions, if is positive, then we know we can factor it.

lets check it anyway.
