Q. Solve using the quadratic formula.v2+6v+8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.v=_____ or v=_____
Write Quadratic Formula: Write down the quadratic formula.The quadratic formula is used to solve equations of the form av2+bv+c=0. The formula is:v=2a−b±b2−4acIn our equation, a=1, b=6, and c=8.
Substitute Values: Substitute the values of a, b, and c into the quadratic formula.v=2(1)−(6)±(6)2−4(1)(8)v=2−6±36−32v=2−6±4
Simplify and Solve: Simplify under the square root and the fraction.v=2−6±2This gives us two solutions when we consider the ± sign.
First Solution: Solve for the first solution using the positive square root.v=(−6+2)/2v=−4/2v=−2
Second Solution: Solve for the second solution using the negative square root.v=(−6−2)/2v=−8/2v=−4
