3x^2 + 3x - 6
First factor out the 3 in front of x^2:
3( x^2 + x - 2 )
Now we can look at the inside of the brackets, and find two numbers that, when multiplied, give -2, and when added, give +1. You will usually find them if you create a list of factors of the constant term (-2 in this case).
2 * -1 = -2
2 + -1 = 1
So the factorization becomes 3(x+2)(x-1)
The equation for the area of a circle is:
A=π*radius squared.
Since radius is half of the diameter.
Diameter/2=radius
Then plug it into the equation.
If the 8 you’re talking about is in inches then it would be 16 feet but if it’s 8 feet then it’s 4 inches
