Please explain to me step by step how to come to the final answer for the following equation:
What you wrote is not an equation, lets assume you mean
2x%5E4-128=0
divide through by 2, and you have
x%5E4+-+64+=+0
Factors to
%28x%5E2-8%29%28x%5E2%2B8%29=+0
the real solutions
x%5E2+=+8
x+=+%2Bsqrt%288%29 = 2%2Asqrt%282%29
and
x+=+-sqrt%288%29 = -2%2Asqrt%282%29
