Quadratic Formula Definition: The quadratic formula is given by x=2a−b±b2−4ac, where a, b, and c are the coefficients of the quadratic equationax2+bx+c=0. In this case, a=3, b=6, and c=3.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. For our equation, the discriminant is 62−4(3)(3).
Discriminant Calculation: Perform the calculation: 62−4(3)(3)=36−36=0.
One Real Solution: Since the discriminant is 0, there is only one real solution to the equation, and it is not necessary to calculate the ± part of the formula. We can proceed with x=−b/(2a).
Substitute Values: Substitute the values of a and b into the formula: x=(2×3)−6.
Final Calculation: Perform the calculation: x=−6/6=−1.
Unique Solution: The solution to the equation 3x2+6x+3=0 is x=−1. Since the discriminant was 0, there is only one unique solution.
