Question

How do you solve the following equation - pi*(x+1)^2 ?

Answer 1

This isn't an equation, it's an expression, and all you can do is simplify....

Multiply out the square using the FOIL method (First, Outside, Inside, Last)

(x+1)(x+1)

x^2 + x + x + 1

(x^2 + 2x + 1)

So now you have

pi(x^2 + 2x + 1)

or

pi*x^2 + 2pi*x + pi

Answer 2

Well, first we need to know what pi*(x+1)^2 is equal to. Otherwise it's an expression and not an equation.
