1. Jawaban 4LL
Nomor 1
= | √2 - 1 |
= (√2 - 1)²
= (√2 - 1)(√2 - 1)
= 2 - 2√2 + 1
= 3 - 2√2
Nomor 2
= | 3 - (-21) |
= (3 - (-21)²
= (3+21)²
= 24²
= 576
Nomor 3
= | -2x + 3 |
= (-2x + 3)²
= (-2x + 3)(-2x + 3)
= 4x² - 12x + 9
Nomor 4
= | ½ x - ⅔ |
= (½ x - ⅔)²
= (½ x - ⅔)(½ x - ⅔)
= ¼ x² - ⅓ x - ⅓ x + 4/9
= ¼ x² - ⅔ x + 4/9
