Question

The roots of 35x²+13x-12=0 are

Answer 1

Answer:

x = - 4/ 5 ; x = 3/7

Step-by-step explanation:

35x²+13x-12=0

7x (5x + 4) - 3(5x + 4) = 0

(5x + 4) (7x - 3) = 0

5x +4 = 0 ;  7x-3 = 0;

x = - 4/ 5 ; x = 3/7

Answer 2

35x2 + 13x - 12 =0

35x2 + 28 x - 15x - 12= 0

7x (5x + 4) - 3 (5x + 4) =0

(5 x + 4 x) (7x - 3x) = 0

5x + 4 =0 or 7x - 3= 0

x = -4/5 or x= 3/7
