Faktor dari p^2 + 5p – 36..??​

Jawaban:

p = 4

Penjelasan dengan langkah-langkah:

p² + 5p – 36 = 0

(p – 4) (p + 9) = 0

p – 4 = 0

p = 4

p + 9 = 0

p = -9

Bukti :

• p = 4

4² + 5(4) – 36 = 0

16 + 20 = 36

36 = 36 ✓

• p = -9

(-9)² + 5(-9) – 36 = 0

-81 + (-45) = 36

-126 = 36 ×

P^2 + 5p -36
= (p-4)(p+9)
p = 4 atau p = -9
