Kak tolong bantu aku ya

Pembahasan dan langkah langkah :

A.X²- 8 X = 0

x ( x – 8 ) = 0

atau

( x – 8 ) = 0

x = 8

Hp = { 0,8 }

B. 16 p²- 36 = 0

( 4p² – 6² ) = 0

( 4p – 6 ) ( 4p + 6 ) = 0

4p – 6 = 0 atau 4p + 6 = 0

p = 6/4 p = – 3/2

p = 3/2

Hp = { – 3/2 , 3/2 }

C.X²- 15 + 56 = 0

( x – 8 ) ( x – 7 )

x = 8 x = 7

D.4m² + 12 + 5 = 0

( 4m + 5 ) ( m + 1 )

m = – 5/4 m = – 1

E. 10 – 23 x- 5x² = 0

5 x ² 23 x – 10 = 0

(x + 5 ) ( 5 x – 2) = 0

x = – 5 U x = 2/5

soal

A. x²-8x = 0

x (x – 8)= 0

x= 0   atau x=  8

B. 16p² – 36 = 0

(4p – 6)(4p + 6) =0

p = 6/4  atau p = – 6/4

p= 3/2  atau p = – 3/2

C.  x² – 15 x + 56 = 0

(x – 7)( x-  8) = 0

x =  7 atau x=  8

D. 4m² +12 m + 5 = 0

(2m  + 1)(2m + 5) = 0

m = -1/2  atau m = – 5/2

E. 10 – 23x – 5x² = 0

(5 +  x)( 2 – 5x) =  0

x = – 5  atau x = 2/5
