Question 1122927
Like as how formed?


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



{{{a(x-h)^2+k=0}}}, simple algebra and not more needed


{{{k(x-a)(x-b)=0}}}, zero-product property, simple algebra and not more needed


{{{ax^2+bx+c=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.)
