Step-by-step explanation:
The polynomial as per the given of the problem is f(x)=3x²-21x+30
Find the roots of this polynomial:
x₁=[-b+√b²-4ac)]/2a and x₂ =[-b-√b²-4ac)]/2a
Plug in : x₁ = [21+√(21²-4(3)(30)]/6 = [21+√81}/6 ; x₁ = 5
and x₂ = [21-√(21²-4(3)(30)]/6 = [21-√81]/6 ; x₂ = 2
Remark: I don't understand where did you bring √5 , it should be 5
//I take it you're trying to find the area or circumference of a circle, so I'll do both.
= area
3.14 * <span>
= 28.26 (2 d.p)
</span>2
r = circumfrence
<span>2 * 3.14 * 3 = 18.84 (2 d.p)</span>
