Q. Use the quadratic formula to solve. Express your answer in simplest form.12v2+13v+1=6vAnswer: v=
Set Equation Equal: First, we need to bring all terms to one side of the equation to set it equal to zero.12v2+13v+1−6v=0This simplifies to:12v2+7v+1=0
Use Quadratic Formula: Now we will use the quadratic formula to solve for v, which is given by:v=2a−b±b2−4acFor our equation, a=12, b=7, and c=1.
Calculate Discriminant: Next, we calculate the discriminant, which is the part under the square root in the quadratic formula:Discriminant = b2−4acDiscriminant = (7)2−4(12)(1)Discriminant = 49−48Discriminant = 1
Apply Quadratic Formula: Since the discriminant is positive, we will have two real and distinct solutions. We can now plug the values of a, b, and c into the quadratic formula:v=2×12−7±1v=24−7±1
Solve for Solutions: We will now solve for the two possible values of v: First solution: v=(−7+1)/24 v=−6/24 v=−1/4
Second solution: v=(−7−1)/24 v=−8/24 v=−1/3
