Matematika SMP Kelas VIII

(2x - 3)² - (y + 7)² = 4x² - 12x + 9 - (y² + 14y + 49)
                            = 4x² - 12x + 9 - y² - 14y - 49
                            = 4x² - y² - 12x - 14y - 40

Answer 2

Verified answer

(2x - 3)^2 - (y + 7)^2
= 4x^2 - 12x + 9 - (y^2 + 14y + 49)
= 4x^2 - 12x + 9 - y^2 - 14y - 49
= 4x^2 - 12x - y^2 - 14y - 40
