Which of the following is the solution to the equation 2x²+x=28=0? A B C x = -4 and x = - -3.5 x = 3.5 and 2 = 4 x = -4 and x = = 3.5 Factor the equation and solve: 2x²+x-28= (x+4) (2x-7)= 0, so x = -4 and = 3.5. Alternatively, substitute the values into the equation and see if the result is true. D x = -3.5 and a = 4 ✓
