Q. Solve using the quadratic formula.2p2+8p+8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.p=_____ or p=_____
Quadratic Formula: The quadratic formula is given by p=2a−b±b2−4ac, where a, b, and c are the coefficients of the terms in the quadratic equationap2+bp+c=0. In this case, a=2, b=8, and c=8.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Here, it is 82−4(2)(8).
Discriminant Calculation: Perform the calculation: 64−64=0.
Apply Quadratic Formula: Since the discriminant is 0, there is only one real solution to the equation. Now, apply the quadratic formula with the discriminant: p=2×2−8±0.
Simplify Expression: Simplify the expression: p=4−8±0.
Divide to Find Solution: Since adding or subtracting 0 does not change the value, we have p=−48.
Divide to Find Solution: Since adding or subtracting 0 does not change the value, we have p=−8/4. Divide −8 by 4 to get the solution: p=−2.
