Y=ax^2+bx+c look at the coefficient of the x^2 term. 1.8k views 3 years ago quadratics. Y = a (x + r1) (x + r2) where a is a known constant, r 1 and r 2. Web to convert the standard form y = ax² + bx + c to vertex form: Extract a from the first two terms: If a is positive, the parabola opens up. If a is negative, then the parabola opens down. Factored form looks like this: Add and subtract (b/(2a))² inside the bracket: Web vertex form looks like this:
Factored form looks like this: 1.8k views 3 years ago quadratics. If a is negative, then the parabola opens down. Web vertex form looks like this: Y = a (x + r1) (x + r2) where a is a known constant, r 1 and r 2. Extract a from the first two terms: Y = a[x² + (b/a)x] + c. Y = a (x + b)2 + c where a, b and c are known constants and x and y are variables. If a is positive, the parabola opens up. Web to convert the standard form y = ax² + bx + c to vertex form: Y=ax^2+bx+c look at the coefficient of the x^2 term.
