Y=x^2-4x-5 in vertex form 161495
Answer The correct answer is y = 8 (x 2)^2 15 Stepbystep explanation I just got the question correct izvoru47 and 241 more users found this answer helpful heart outlined Thanks 146 star 1 Answer Massimiliano In this way y = x2 4x −1 ⇒ y = x2 4x 4 −4 −1 ⇒ y = (x 2)2 −5 ⇒ y 5 = (x 2)2 The vertex is V ( − 2, − 5) Answer link To convert a quadratic from y = ax 2 bx c form to vertex form, y = a(x h) 2 k, you use the process of completing the square Let's see an example Let's see an example Convert y = 2x 2 4x 5 into vertex form , and state the vertex Write Each Function In Vertex Form 1 Solution Answer Y X Y=x^2-4x-5 in vertex form
