Step-2 : Find two factors of 12 whose sum equals the Solve Using the Quadratic Formula x^2-3x-3=0. Identify the coefficients a, b and c and substitute those values into the quadratic formula to find x=-1 or x=4. set each term = 0.This is achieved by dividing both sides of the equation by 3. Two numbers r and s sum up to -3 exactly when the average of the two numbers is \frac{1}{2}*-3 = -\frac{3}{2}. Then, the 2 real roots are: -1 and 3. Simultaneous equation. Simplify both sides of the equation. 3x2 − 4x − 4 = 0 3 x 2 - 4 x - 4 = 0. In the quadratic formula for quadratic equation ax^2+bx+c=0 x= (-b+-sqrt (b^2-4ac))/ (2a) the discriminant is the part in the radical sign b^2-4ac It provides a simple test for the nature and number of solutions because: the solutions can only be real if the value of b^2-4ac is a Graph f (x)=x^2-3x-4. This sum is 3 = -b.. Any value that is multiplied by 0, will give 0 as the answer. Ecuación de segundo grado y se resuelve usando la formula .
