1) 10x^2 + 5 = 010x^2 = -5x^2 = -5/10x^2 = -0.5x = ±√(-0.5)x = ±i√0.5x = ±i√(1/2)x = ±i√2/2Ответ: x = ±i√2/2
2) 25 - 100x = 0-100x = -25x = -25/-100x = 1/4Ответ: x = 1/4
3) 2x^2 - 8 = 02x^2 = 8x^2 = 8/2x^2 = 4x = ±√4x = ±2Ответ: x = ±2
1) 10x^2 + 5 = 0
10x^2 = -5
x^2 = -5/10
x^2 = -0.5
x = ±√(-0.5)
x = ±i√0.5
x = ±i√(1/2)
x = ±i√2/2
Ответ: x = ±i√2/2
2) 25 - 100x = 0
-100x = -25
x = -25/-100
x = 1/4
Ответ: x = 1/4
3) 2x^2 - 8 = 0
2x^2 = 8
x^2 = 8/2
x^2 = 4
x = ±√4
x = ±2
Ответ: x = ±2
