Question

Tentukan faktor dari 6x² + 5x - 4. pake caranya!

Answer 1

P.q = a.c
p+q = b

p.q= -24
p+q=5

p= 8
q= -3

((6x+8)(6x-3)) ÷ 6 = (3x+4)(2×-1)

÷ itu per

Answer 2

6x² + 5x - 4 = 0

Rumus abc
[b ± √(b² - 4ac)] / 2a
= [5 ± √(5² - 4(6)(-4))] / 2(6)
= [5 ± √(25 - (-96))] / 12
= [5 ± √(25 + 96)] / 12
= [5 ± √121] / 12
= [5 ± 11] / 12

⇒
(5 + 11) / 12
= 16 / 12
= 1,33

⇒
(5 - 11) / 12
= -6 / 12
= -1/2

Jadi, HP : {-1/2 , 1,33}
