Web vertex form looks like this: Y = a (x + b)2 + c where a, b and c are known constants and x and y are variables. Y=ax^2+bx+c look at the coefficient of the x^2 term. Factored form looks like this: Extract a from the first two terms: If a is negative, then the parabola opens down. If a is positive, the parabola opens up. Web to convert the standard form y = ax² + bx + c to vertex form: Add and subtract (b/(2a))² inside the bracket: 1.8k views 3 years ago quadratics.
