When the equation x2-2x-5 = 0 is solved by the collocation method, the original equation should be transformed into___ ．

When the equation x2-2x-5 = 0 is solved by the collocation method, the original equation should be transformed into___ ．

The formula is x2-2x + 1 = 5 + 1, that is, (x-1) 2 = 6, so the answer is (x-1) 2 = 6

The equation (x + 1) 2 = 2x is reduced to the general form as______ ．

Using the complete square formula, we can get (x + 1) 2 = x2 + 2x + 1, so the equation (x + 1) 2 = 2x can be transformed into x2 + 2x + 1 = 2x, the term shifting can get x2 + 2x + 1-2x = 0, and the term merging can get X2 + 1 = 0. The general form of the original equation is x2 + 1 = 0

What is 4 (- X & # 178;) - # 179; equal to?

4（-x²）³
=4*(-1)³(x²)³
=-4x^6

What is x · X & # 179; + X & # 178; · X & # 178; equal to

=X^4+x^4
=2x^4
Hope to adopt it!
