Answer:
Step-by-step explanation:
If a quadratic equation is defined as
.... (1)
then the quadratic formula is
The given quadratic equation is
It can we written as
.... (2)
On comparing (1) and (2) we get
Substitute these values in the quadratic formula.
Taking out common factors.
Two roots are
and 
We know that
So
Therefore, root is positive and is negative.

Answer:
im pretty sure its ryan had a headstart of 3 or 10 meteres
Step-by-step explanation:
Answer:
x^2 + (x + 2)^2 = 202
x^2 + x^2 + 4x + 4 = 202
2x^2 + 4x + 4 = 202
2x^2 + 4x - 198 = 0
x^2 + 2x - 99 = 0
x = -2/2 ± √((2/2)^2 - (-99))
x = 9 or x = -11
-11 is not a positive number so the number is 9.
