= ( x - y + z) x ( ( x - y + z) - 2 ( z - y) ) + ( z - y) ^ 2 = ( x - y + z ) x ( x + y - z ) + ( z - y ) ^2 = x ^ 2 - ( z - y) ^2 + ( z - y ) ^2 = x^ 2

6²:4.3+2.5²

= 36 : 4 . 3 + 2.25

= 9.3 + 50

= 27 + 50

= 77

(x²-x)²=12+4x-4x²

=>(x²-x)²+4x²-4x-12=0

=>x⁴-2x³+5x²-4x-12=0

=>(x-2)(x+1)(x²-x+6)=0

\(\Rightarrow\orbr{\begin{cases}x=2\\x=-1\end{cases}\left(tm\right)}\)
