saya mohon jawab secepatnya. tolong isi dengan caranya 4a²+34a+16=0

Bab Persamaan Kuadrat
Matematika SMP Kelas VIII

4a² + 34a + 16 = 0
2a² + 17a + 8 = 0
2a² + a + 16a + 8 = 0
a(2a + 1) + 8(2a + 1) = 0
(2a + 1) (a + 8) = 0
2a + 1 = 0
2a = -1
a = -1/2

a + 8 = 0
a = -8

HP = { -8, -1/2 }

Bab Persamaan Kuadrat

4a^2 + 34a + 16 = 0

FPB = 2

2(4a^2/2 + 34a/2 + 16/2 )= 0
2(2a^2 + 17a + 8 )= 0
2(2a^2 + 16a + a + 8) = 0
2(2a(a+8) + (a + 8) = 0
2(a+8) (2a + 1) = 0
2(a+8)(2a + 1) = 0


HP=
a + 8 = 0
a = -8

Or

2a + 1 = 0
2a = -1
a = -1/2

HP ={-1/2,-8}
