Question

3x² - 2x-8=0 solve by factorisation method

​

Answer 1

use the quadratic formula

Answer 2

Answer:

x=-4/3 & x =2

Step-by-step explanation:

3x²-2x-8 = 0

a=3 b=-2 c= -8

product = -24

sum = -2

             -24 = -6 * 4

             -2   = -6+4

(3x+4)     (x-2) are the 2 roots                                    (3x-6)=(x-2)

x= -4/3  &  x=2 are the solutions
