Question

Resolvam:
(3x-2) . (2x-3)= 0​

Answer 1

(3x-2) . (2x-3)= 0

(3x-2)=0 => 3x=2 => x' = 2/3 ✓

(2x-3)= 0 => 2x=3 => x"= 3/2 ✓

S: {2/3 , 3/2}

Answer 2

Resposta:

S = { 2/3 , 3/2}

Explicação passo-a-passo:

( 3x - 2) x ( 2x -3)= 0

6x² - 9x -4x +6 = 0

6x² -13x +6= 0

a = 6

b = -13

c = 6

Δ= b² -4.a.c

Δ=(-13)²- 4 x 6 x 6

Δ= 169 -144

Δ= 25

x = -b ±√Δ / 2.a

x= -(-13)±√25 / 12

x1 = 13+5/12

x1 = 18/12 = 3/2

x2 = 13-5/12

x2 = 8/12 = 2/3
