rozwiąż równanie

A). (3-x)²-(x+⅓)²=²/₉

B). 4(½x-3)² =(2-x)²

C). (6+⅓x)(-⅓x+6)+(⅓x-4)²=4

D). (-4x-3)(4x-3)+8(1-√2x)²=1

Answer 1

A) 9-6x+x²-(x²+2/3x+1/9)=2/9

9-6x+x²-x²-2/3x-1/9=2/9

-6i2/3x=2/9+1/9-9

-6i2/3x=-8i2/3

-20/3x=-26/3

x= 1,3

B) 4(1/2x-3)²=(2-x)²

4(1/4x²-3x+9)=4-4x+x²

x²-12x+36=4-4x+x²

x²-12x+4x-x²=4-36

-8x=-32

x=4

C) (6+1/3x)(-1/3x+6)+(1/3x-4)²=4

(6+1/3x)(6-1/3x)+1/9x²-8/3x+16=4

36-1/9x²+1/9x²-8/3x=4-16

-8/3x=-12-36

-8/3x=-24

x=9

D) (-4x-3)(4x-3)+8(1-√2x)²=1

-(4x+3)(4x-3)+8(1-2²√2x+2x²)=1

-(16x²-9)+8-16√2x+16x²=1

-16x²+9+8-16√2x+16x²=1

16√2x=1-17

16x√2=-16

x√2=-1

x= √2/2
