Like as how formed?

Basic intermediate algebra instruction is where or the way solving them is learned.


a%28x-h%29%5E2%2Bk=0, simple algebra and not more needed

k%28x-a%29%28x-b%29=0, zero-product property, simple algebra and not more needed

ax%5E2%2Bbx%2Bc=0, see your lessons about Completing The Square in order to learn to solve an equation in this form. (Unless your example were factorable; and then you would use zero-product principle.)
