Best ResponseYou've already chosen the best response.0THere are many ways my prefer way is to use quadratic formula. Depending on what they want u to use tho they may not like it. BUT 2x2  20 = 3x 2x2  20  3x=0 just subtract 3x from both sides. 2x2  3x 20 =0 rearrange now use quadratic equation ax2 + bx +c =0 2x2  3x 20
