WebA parabola is defined as 𝑦 = 𝑎𝑥² + 𝑏𝑥 + 𝑐 for 𝑎 ≠ 0 By 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 − … WebFirst we need to identify the values for a, b, and c (the coefficients). First step, make sure the equation is in the format from above, ax^2 + bx + c = 0 ax2 +bx +c = 0: x^2+4x-21=0 x2 + … WebTo solve this, you would use the zero product property. If you make one of the parentheses equal to zero then the whole left side is equal to zero (because zero multiplied by anything is zero). So you'd set the first set of parentheses like so: (x-2)=0. Then to isolate "x", you would add 2 to both sides to get x=2. hideaway country club rentals
