Best ResponseYou've already chosen the best response.1Bring 14 to the left: 2x² + x  14 = 0 The quadratic formula is x = (b ± √(b²  4ac))/2a. The quadratic equation is ax² + bx + c = 0. Furthermore, by using the formulas here, we have: a = 2 b = 1 c = 14 x = (1 ± √(1²  4(2)(14)))/2(2) x = (1 ± √(1 + 112))/4 x = (1 ± √(113))/4 By calculator, we have: x ≈ 2.41 and x ≈ 2.91
