Question

65x^2-x-10 find its zeros

Answer 1

65x^2-x-10

65x^2-26x+25x-10

13x(5x-2)+5(5x-2)

(13x+5)(5x-2)

Answer 2

Answer:

x = -5/13   and   x = 2/5

Step-by-step explanation:

65x^2-x-10  =0

65x^2-26x+25x-10  =0

13x(5x-2)+5(5x-2)  =0

(13x+5)(5x-2) =0

13x +5 =0  or   5x - 2 =0

13x =-5  or  5x = 2

x = -5/13   or   x = 2/5
