Rozwiąż równanie (x-4)²= (x-4)(2x-1)Rozwiąż równanie (4-3x)²= 16-3x²
1.
(x-4)²= (x-4)(2x-1)
(x-4)(2x-1)-(x-4)²=0
(x-4)(2x-1-x+4)=0
(x-4)(x+3)=0
x=4 lub x=-3
===============
2.
(4-3x)²= 16-3x²
(4-3x)²= 4²-3x²
(4-3x)²= (4-3x)(4+3x)
(4-3x)²-(4-3x)(4+3x)=0
(4-3x)(4-3x-4-3x)=0
(4-3x)(-6x)=0
x=3/4 lub x=0
