Answer 1

Verified answer

3x² -14x-5= 0
3x² -15x+x-5 = 0
(3x² -15x)+(x-5)= 0
3x(x-5)+1(x-5) =0
(3x+1)(x-5) = 0

Maka akar2nya
X = -1/3
X = 5

Answer 2

Verified answer

Diketahui :
* persamaan; 3x² - 14x - 5 = 0
ditanya :
* akarnya?
jawab;
* 3x² - 14x - 5 = 0
( 3x + 1 ) ( x - 5 )
* 3x + 1 = 0
3x = -1
x = -1/3
* x - 5 = 0
x = 5

* jadi akarnya =
x = -1/3
x = 5
