Tentukan akar-akar persamaan kuadrat berikut. A)x²+15+14=0 B)x²-3x-40=0 C)x²-9x+18=0 D)x²-2x=24 E)x²=-2x+24 TLG DIJB! PAKAI CARACARA KEBAWAH ,, TLGBANTU SAYA PL

A)x²+15+14=0
(x+14)(x+1) = 0
x+14=0 => x=-14
x+1=0 => x=-1

B)x²-3x-40=0
(x-8)(x+5)=0
x-8=0 => x=8
x+5=0 => x=-5

C)x²-9x+18=0
(x-6)(x-3)=0
x-6=0 => x=6
x-3=0 => x=3

D)x²-2x=24
x2-2x-24=0 => (x-6)(x-4)=0
x-6=0 => x=6
x-4=0 => x=4

E)x²=-2x+24
x2+2x-24=0 => (x+6)(x-4)=0
x+6=0 => x=-6
x-4=0 => x=4


Semoga membantu yaa :)
