(10x +5)² = 100x(x+1) + 25
100x² + 100x + 25 = 100x² + 100x +25
100x² + 100x +25 - 100x² -100x -25 =0
0 = 0
Brak obliczenia x
Sprawdź czy dobrze napisałeś równanie
100x {do kwadratu} + 100x + 25 = 100x {do kwadratu} + 100 + 25
100x {do kwadratu} + 100x - 100x {do kwadratu} = 100 + 25 - 25
100x = 100 /: 100
x = 1
10x + 5 = 10 * 1 + 5 = 10 + 5 = 15
