Tentukan nilai a,b,c dari persamaan a.2×2-5×+3=0 b.x²-9=0 c.-x²+4×=0​

Penjelasan dengan langkah-langkah:

a.2x² – 5x + 3 = 0

a = 2 , b = -5 , c = 3

Nilai X1 + X2 = -b/a

= -(-5)/2

= 5/2

Nilai X1.X2 = c/a

= 3/2

b.x² – 9 = 0

x² – 9 – 0

a = 1 , b = -9 , c = -0

Nilai X1 + X2 = -b/a

= -(-9)/1

= 9/1

Nilai X1.X2 = c/a

= -0/1

= 0

c.-x² + 4x = 0

-x² + 4x – 0

a = -1 , b = 4 , c = -0

Nilai X1 + X2 = -b/a

= -4/-1

= 4

Nilai X1.X2 = c/a

= -0/-1
