how do you solve a polynomial equation

Question

 

x^{2 +} 8x + 16 =

Answer 1

To solve this equation, you could factor or use the quadratic formula.

It would be much easier to factor in this case.

x^2 + 8x + 16 = 0

(x + 4)*(x + 4) = 0

Now, we can set either of the terms equal to zero:

(x + 4) = 0

Solving for x we have:

x = -4
