Question

Tolong dong sekalian langkah nya

Answer 1

3x^2 + 2x - 2=0
bntuk umum ax^2 + bx + c = 0
pake rmus abc = -b + - akar D / 2a
cari Determinan (D) dulu = b^2 - 4 ac
4 - 4 × 3 (-2) = D
28 = D
x 1 x2 = - b + -akar D / 2a
x1 x2 = -2 + - akar 28 / 6
x1 x2 = -2 + - 2 akar 7 / 6
x1 x2 = -1 + - akar 7 / 3
jawabnya B
