Question 996673: I've been trying to do this problem and not sure on the formula, could you please help me?
write the polynomial function P in factored form and in standard form by using the given information.
degree=2;P(O)=3;zeros:1,3/7

Included point is (0,3).
P%28x%29=a%28x-1%29%28x-3%2F7%29
-
Use the included point to find the factor a.

Some steps although with a still as variable, to get to the needed term for completing the square,
a%28x%5E2-%287%2F7%29x-%283%2F7%29x%2B3%2F7%29
a%28x%5E2-%2810%2F3%29x-3%2F7%29
-
Use %2810%2F%282%2A3%29%29%5E2=%2810%2F6%29%5E2 to complete the square for putting P into standard form. Note that this term is also %285%2F3%29%5E2.
