1) (x - 2)² + 4(x - 3) =(x² + x - 3)
2) (x - 2)² – 2(x + 1) = (x - 1)(x - 2)
3) (x - 2)² + 3(x - 5) = x² + 3x - 3
4)(x - 3)² + (x + 3)² = 2 (x² +9)
5) (3x - 1)² + (3x +1)² = 2(9x² + 4) + 1
6) (x - 1)(x - 2) + (2x + 1)² = 5x²

1) (x - 2)² + 4(x - 3) =(x² + x - 3)
2) (x - 2)² – 2(x + 1) = (x - 1)(x - 2)
3) (x - 2)² + 3(x - 5) = x² + 3x - 3
4)(x - 3)² + (x + 3)² = 2 (x² +9)
5) (3x - 1)² + (3x +1)² = 2(9x² + 4) + 1
6) (x - 1)(x - 2) + (2x + 1)² = 5x²

1) (x + 1)² + 2x = x(x + 1) + 6
2) 3 - 4x(3 - 2x) = 8x² + x - 30
3) x²-x(5 - x) = 8
4) (x - 1)² - 36 = 0
5) (3x - 1)(4x - 3) + 2x(6x - 1) = 2(2x + 7)
