Question

Someone please help me? I don't know how to solve these :/

Answer 1

`2x^2-x-6=0\\ 2x^2-4x+3x-6=0\\ 2x(x-2)+3(x-2)=0\\ (2x+3)(x-2)=0\\ x=-(3)/(2) \vee x=2`

Answer 2

`2x^2 - x - 6 = 0`


`(2x - 3) (x + 2) = 0`


`2x - 3 = 0`


`2x = 3`


`x = (3)/(2)`


`x + 2 = 0`


`x = -2`


`x = (3)/(2) , 2`
