P. 22
Berechne!
a) (4x – 1)² = (x – 4)² x² und x b) (x – 4)² + (x – 3)² = 61 nur x²
ja nein
c) (5x + 2)² = (3x + 4)² + 4(1 – x) d) (x + 5)² + (x + 3)² = 100
e) (x + 5)(x – 5) = (2 – x)(2 + x) + 3 f) (x – 1)² – (2x – 2) = –(x – 3)²
x² – 5x +6 = 0; L = { 2; 3 } x² + 8x – 33 = 0; L = { 3; –11 } f) d) b) x² – 7x – 18 = 0; L = { 9; –2 } 2x²=32; L = { 4; –4 } 6x²=16; L = { 1; –1 } 15x²=15; L = { 1; –1 } e) b) a)
