 Question 86176: Can you please help with this equation? Find the roots of 3x^2+2x-4=0. Thank you so much for your help.Answer by jim_thompson5910(28595)   (Show Source): You can put this solution on YOUR website!Starting with the general quadratic the general form of the quadratic equation is: So lets solve Plug in a=3, b=2, and c=-4 Square 2 to get 4 Multiply to get Combine like terms in the radicand (everything under the square root) Simplify the square root Multiply 2 and 3 to get 6 So now the expression breaks down into two parts or Which approximate to or So our solutions are: or Notice when we graph we get: when we use the root finder feature on our calculator, we find that and .So this verifies our answer
