Q. Solve using the quadratic formula.6v2+9v−8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.v=_____ or v=_____
Plug Values into Formula: Plug the values of a, b, and c into the quadratic formula, v=2a−b±b2−4ac. So, v=2⋅6−(9)±(9)2−4⋅6⋅(−8).
Simplify Square Root: Simplify inside the square root: (9)2−4⋅6⋅(−8)=81+192.This gives us 273.
Calculate Possible Solutions: Now, calculate the two possible solutions for v.v=12−9±273.
Simplify Solutions: Simplify the solutions. v=12−9+273 or v=12−9−273.
Round to Nearest Hundredth: Round the values of v to the nearest hundredth if necessary.v≈(−9+16.52)/12 or v≈(−9−16.52)/12.v≈7.52/12 or v≈−25.52/12.
Divide to Get Decimal Values: Finally, divide to get the decimal values. v≈0.63 or v≈−2.13.
