Let's check the first polynomial , that is

We need to factor it first and for that we have to do grouping and factoring .

TO find the roots, we need to set P(x) to 0, that is

SO the correct option is A .
Answer:
314.16
Step-by-step explanation:
Since the diameter is 15 and the radius is only half of the diameter the radius is ten. Now the the equation to find area in a circle is 3.14 (or the pi symbol on your calculator) r squared which would mean 3.14*10^2 which would give you your answer
The answer is -2-4
