3. Selesaikan dengan cara melengkapkan kwadrat sempurna x² + 2x-35 = ​

Jawaban:

HP(6,83,-4,83)

Penjelasan dengan langkah-langkah:

x²+2x-35=0

x²+2x=35

x²+2x-(1/2(2)²=35-(1/2(2)²

x²+2x-(1)²=35-(1)²

(x+1) (x+1)=35-1

(x+1)²=34

x+1=+-akar34

x1,2=1+-5,83

x1=1+5,83

x1=6,83

x2=1-5,83

x2=-4,83 HP(6,83,-4,83)
