При решении данных уравнений найдем значения x:
1) x^2 - (x-5)^2 = 10x^2 - (x^2 - 10x + 25) = 10x^2 - x^2 + 10x - 25 = 1010x - 25 = 1010x = 35x = 3.5
2) (x+3)^2 - x = 33x^2 + 6x + 9 - x = 33x^2 + 5x - 24 = 0(x + 8)(x - 3) = 0x = -8 или x = 3
3) (x+12)^2 = x(x+8)x^2 + 24x + 144 = x^2 + 8xx^2 - 16x + 144 = 0(x - 12)^2 = 0x = 12
4) (x-3)(x+1) = (x-2)^2x^2 - 2x - 3 = x^2 - 4x + 42x = 7x = 3.5
Итак, мы нашли значения x: x = 3.5, x = -8, x = 3, x = 12.
При решении данных уравнений найдем значения x:
1) x^2 - (x-5)^2 = 10
x^2 - (x^2 - 10x + 25) = 10
x^2 - x^2 + 10x - 25 = 10
10x - 25 = 10
10x = 35
x = 3.5
2) (x+3)^2 - x = 33
x^2 + 6x + 9 - x = 33
x^2 + 5x - 24 = 0
(x + 8)(x - 3) = 0
x = -8 или x = 3
3) (x+12)^2 = x(x+8)
x^2 + 24x + 144 = x^2 + 8x
x^2 - 16x + 144 = 0
(x - 12)^2 = 0
x = 12
4) (x-3)(x+1) = (x-2)^2
x^2 - 2x - 3 = x^2 - 4x + 4
2x = 7
x = 3.5
Итак, мы нашли значения x: x = 3.5, x = -8, x = 3, x = 12.
