6 × kuadrat -2 × - 4=0? 8 × kuadrat -2×-10=0? 6 × kuadrat -5×-6=0? tolonggg bantuuu:

1. 6x^2 -2x -4 = 0
=3x^2 -x -2 = 0
=(3x+2)(x-1) = 0

Maka X = -2/3 & 1

2. 8x^2 -2x -10 = 0
=4x^2-x-5 = 0
=(4x-5)(x+1) = 0

Maka X = 5/4 & -1

3. 6x^2 -5x-6 = 0
=(6x+4)(6x-9) = 0
=(6x+4)(x-9/6)= 0

Maka x = -2/3 & 3/2

Maaf jika ad kesalahan
