XIntercepts From Vertex Form of a Quadratic Equation YouTube
Y Intercept In Vertex Form. If a is negative, then the parabola opens down. Y = a (x + r1) (x + r2) where a is a known constant, r 1 and r 2.

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