Q. Solve using the quadratic formula.3v2+7v+3=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.v=_____ or v=_____
Quadratic Formula Explanation: The quadratic formula is given by v=2a−b±b2−4ac, where a, b, and c are the coefficients of the quadratic equationav2+bv+c=0. In this case, a=3, b=7, 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 (7)2−4(3)(3).
Discriminant Calculation: Perform the calculation: (7)2−4(3)(3)=49−36=13.
Plug into Quadratic Formula: Now that we have the discriminant, we can plug it into the quadratic formula along with the values of a and b. This gives us two possible solutions for v: v=2×3−7±13.
Simplify Solutions: Simplify the solutions: v=6−7±13.
Calculate Decimal Values: Since 13 cannot be simplified to an integer or a simple fraction, and the problem asks for decimals rounded to the nearest hundredth if necessary, we will calculate the decimal values of the two solutions.
First Solution Calculation: First solution: v=6−7+13≈6−7+3.61≈6−3.39≈−0.57 (rounded to the nearest hundredth).
Second Solution Calculation: Second solution: v=6−7−13≈6−7−3.61≈6−10.61≈−1.77 (rounded to the nearest hundredth).
