Graphing quadratic equations in factored form
WebApr 1, 2010 · This video deals with solving quadratic functions. It does not involve the use of the quadratic equation; rather, only factored equations are used. The speaker starts out with a factored quadratic equation. … WebA quadratic equation can be written in the form: ax2+ bx+ c= 0. The arepresents the coefficient (the number) in front of the x2variable. The brepresents the coefficient in front of the xvariable and cis the constant. a. For example, in the equation 2x2+ 3x+ 5 = 0, the ais 2, the bis 3, and the cis 5. b.

WebMar 1, 2024 · Factored Form of Quadratic Equation: y=a (x-r_1) (x-r_2) y = a(x−r1)(x−r2) In factored form, we can see the zeros, also called x x -intercepts, are r_1 r1 and r_2 r2. Our variables remain x x and y y, and a … 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.
