Q. Solve using the quadratic formula.p2+6p+9=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.p=_____ or p=_____
Quadratic Formula Explanation: The quadratic formula is given by p=2a−b±b2−4ac, where a, b, and c are the coefficients from the quadratic equationap2+bp+c=0. In this case, a=1, b=6, and c=9.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Here, it is 62−4(1)(9).
Discriminant Calculation: Perform the calculation: 36−4(1)(9)=36−36=0.
Real Solution Determination: Since the discriminant is 0, there is only one real solution to the equation, and it is not necessary to use the ± symbol in the quadratic formula. The solution is p=−b/(2a).
Substitute Values: Substitute the values of b and a into the formula: p=−6/(2⋅1)=−6/2=−3.
Final Solution: The solution to the equation p2+6p+9=0 is p=−3. Since the discriminant was 0, this is the only solution.
