Graphing quadratic equations in factored form
WebBy factoring out 𝑎 and completing the square, we get 𝑦 = 𝑎 (𝑥² + (𝑏 ∕ 𝑎)𝑥) + 𝑐 = = 𝑎 (𝑥 + 𝑏 ∕ (2𝑎))² + 𝑐 − 𝑏² ∕ (4𝑎) With ℎ = −𝑏 ∕ (2𝑎) and 𝑘 = 𝑐 − 𝑏² ∕ (4𝑎) we get 𝑦 = 𝑎 (𝑥 − ℎ)² + 𝑘 (𝑥 − ℎ)² ≥ 0 for all 𝑥 So the parabola will have a vertex when (𝑥 − ℎ)² = 0 ⇔ 𝑥 = ℎ ⇒ 𝑦 = 𝑘 𝑎 > 0 ⇒ (ℎ, 𝑘) is the minimum point. 𝑎 < 0 ⇒ (ℎ, 𝑘) is the maximum point. WebIf you have a general quadratic equation like this: ax^2+bx+c=0 ax2 + bx + c = 0 Then the formula will help you find the roots of a quadratic equation, i.e. the values of x x where this equation is solved. The quadratic formula x=\dfrac {-b\pm\sqrt {b^2-4ac}} {2a} x = 2a−b ± b2 − 4ac It may look a little scary, but you’ll get used to it quickly!
