Step-by-step solution
4 stepsLet the roots of the quadratic equation be and .
Write down the relationships between the roots and the coefficients of a quadratic equation.
For a quadratic equation of the form , the sum of the roots is and the product of the roots is .
We can also consider a monic quadratic equation (where ), which is .Use the given information to find the sum and product of the roots.
The problem states that the sum of the roots is 2, so .
The problem states that the product of the roots is 3, so .Substitute these values into the monic quadratic equation formula.
Using the formula , we substitute the values from Step 2.
Write the final equation.
The equation is .
x^2 - 2x + 3 = 0
