Jawaban:

D = 79

Penjelasan dengan langkah-langkah:

tinggal masukan a,b,c ke rumus Diskriminan

x² + 5x – 14 = 0

a = 1 , b = 5 c = -14

D = b² – 4ac

D = 5² – 4(1)(-14)

D = 25 -(-54)

D = 25 + 54

D = 79

1. Diket :

x² + 3x – 15 = 0

a = 1

b = 3

c = -15

Jadi :

5a + 2b + c

5(1) + 2(3) + (-15)

5 + 6 – 15

-4 (B)

2. 2x² – 10x = 0

2x (x-5) = 0

2x = 0 atau x-5 = 0

x = 0 atau x = 5

Jadi jawaban yang benar adalah option (C)

Jawaban:

real dan kembar

Penjelasan dengan langkah-langkah:

x² – 6x + 9 = 0

coba kita faktorkan

x² – 6x + 9 = 0

(x-3)(x-3) = 0

x = 3

jadi akar akar dari persamaan kuadrat diatas adalah 3,

angka 3 adalah bilangan real

dan kedua akar sama yaitu 3

jadi jenis akar dari pers kuadrat diatas adalah Real dan Kembar

Penjelasan dengan langkah-langkah:

ax²+bx+c = 0

X1+X1 = -b/a

x1.x2 = c/a

5. -5/1

6. 7/2

7. (x1²+x2²) = (X1+X2)²-2x1x2= 2²- 2(-8) = 4+16 = 20
