x^34x^24x+16 x^2( x  4) + 4( x + 4) = 0 (x + 4) ( x^2 4) = 0 x = 4, x =2, x = =2

using the rational root theorem or p/q, you find that for 2,2,4 values for x you get zero. the rational root theorem is done by finding all that factors of 16/1 and inputing the factors back to the equation. the factors that gives you zero are the numbers that solve the problem.
