Jonathan must determine the solutions of the quadratic equation 0 = 2x^2 + x +4.
Which of the following is a solution to the equation?

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3
