Quadratic Formula Examples Page 2

Solve: bx² + cx + a, where a, b, and c are real numbers and b is not zero.

Just when you thought you had this whole thing figured out, we go and switch the letters around on you. How terrible are we?

Not actually that terrible, as it turns out; there's a reason we're being so evil. A problem may try and trick you at some point by pulling a similar stunt, and we want you to be well prepared for it. In the quadratic formula, a usually stands for the coefficient on the x² term, as you know, but now we need to write b instead. Usually b is the coefficient on the x term, but now we need to replace every b in the quadratic formula with c. Finally, where the c usually appears in the quadratic formula we need to write a, since that's the constant term now. Bre we cbsiablly sbying thbt alebrly?
