1) Using the quadratic equation x2 - 6x + 8 = 0, perform the following tasks
The equation is in this form: highlight%28ax%5E2%2Bbx%2Bc=0%29
b) Solve by using the quadratic formula.
The Quadratic formula is: highlight%28x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a%29
a=1, b=-6, and c=8
x=%28-%28-6%29%2B-sqrt%28%28-6%29%5E2-4%281%29%288%29%29%29%2F%282%281%29%29
x=%286%2B-sqrt%2836-32%29%29%2F2
x=%286%2B-sqrt%284%29%29%2F2
x=%286-2%29%2F2 or x=%286%2B2%29%2F2
x=4%2F2 or x=8%2F2
Answer:
highlight%28x=2%29 or highlight%28x=4%29
Happy Calculating!!!
