tentukan himpunan penyelesaian dari persamaan kuadrat berikut: a.p2-16=o b.x2+2x-15=0

a.p² - 16 = 0
(p - 4)(p + 4) = 0
p = 4 atau p = -4

Hp = {-4,4}

b.x² + 2x - 15 = 0
(x + 5)(x - 3) = 0
x = -5 atau x = 3

Hp = {-5, 3}

A.)
p^2 - 16 = 0
(p - 4)(p + 4) = 0
p1 - 4 = 0
P1 = 4

P2 + 4 = 0
P2 = -4

Hp = {-4,4}

B.)
x^2 + 2x - 15 = 0
(x + 5)(x - 3) = 0

x1 + 5 = 0
x1 = -5

x2 - 3 = 0
x2 = 3

Hp = {-5, 3}

Kalau boleh jadikan jawaban terbaik yah.
