x^212 x+4 = 0 Subtract 4 from both sides: x^212 x = 4 Add 36 to both sides: x^212 x+36 = 32 Factor the left hand side: (x6)^2 = 32 Take the square root of both sides: sqrt(x6) = 4 sqrt(2) Eliminate the absolute value: x6 = 4 sqrt(2) or x6 = 4 sqrt(2) Add 6 to both sides: x = 64 sqrt(2) or x6 = 4 sqrt(2) Add 6 to both sides: x = 64 sqrt(2) or x = 6+4 sqrt(2)
