Factor out 2x in the first and 9 in the second group. To solve this type of quadratic equation, use shortcut. It can save you a lot of time and work. We’ll solve this two ways: By completing the square and using the quadratic formula. 2x2 + 7x +9 = 0. First divide everything by 2, since a cannot have. Enter the equation you want to solve using the quadratic formula. The quadratic formula calculator finds solutions to quadratic equations with real coefficients. For equations with real. #2x^2+7x+9# is of the form #ax^2+bx+c#, with #a=2#, #b=7# and #c=9#. The discriminant #delta# is given by the formula: Starting with a quadratic equation in standard form, ax² + bx + c = 0 divide each side by a, the coefficient of the squared term. Subtract the constant term c/a from both sides. Free math problem solver answers your algebra, geometry, trigonometry, calculus,. Use the quadratic formula to find the solutions.
