Rozwiąż równanie.a) (3x - 1)² = 9x² - 2
b) 4x² = (5 - 2x)²
a) 9x²-6x+1=9x²-2
9x²-9x²-6x=-2-1
-6x=-3 | : -6
x=0,5
b) 4x²=25-20x+4x²
20x=25 | :20
x=1,(2)
a) 3x^2 - 2* 3x +1 = 9x^2 - 2
3x^2 - 6x +1 = 9x^2 - 2
3x^2 - 9x^2 - 6x = -1
-6x^2 - 6x = -1
b) 4x^2 = 25 - 2* 10x + 2x^2
4x^2 = 25 - 20x + 2x^2
4x^2 - 2x^2 + 20x = 25
