You must remember that a polynomial is written like so...
ax^2 + bx + c
In this case...
a = 1
b = 3
c = -10
To factor you must find two numbers who both add up to b (3) AND multiply to c (-10)
-2 + 5 = 3
-2 * 5 = -10
so...
(x - 2)(x + 5)
To find the zero you must set each factor equal to zero and solve for for x like so...
x - 2 = 0
x = 2
x + 5 = 0
x = -5
Hope this helped!

The answer is 567.4 π m².
The surface area of the sphere with radius r is: A = 4 π r²The volume of the sphere with radius r is: V = 4/3 π r³
Step 1. Calculate the radius from the volume:V = 4/3 π r³ = 2,254 π m³r³ = (2,254 π) / (4/3 π)r³ = 2,254 π/π * 3/4r³ = 2,254 * 3/4r³ = 1,690.5r = ∛1,690.5r = 11.91 m
Step 2. Calculate the surface area using the r:A = 4 π r²A = 4 π 11.91²A = 567.4 π m²
