Q. Solve using the quadratic formula.6h2−9h−5=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.h=_____ or h=_____
Identify coefficients: Identify the coefficients a, b, and c in the quadratic equation6h2−9h−5=0. The quadratic equation is in the form ah2+bh+c=0. For our equation, a=6, b=−9, and c=−5.
Substitute values into formula: Substitute the values of a, b, and c into the quadratic formula h=2a−b±b2−4ac. The quadratic formula is h=2⋅6−(−9)±(−9)2−4⋅6⋅(−5).
Simplify expression inside square root: Simplify the expression inside the square rootb2−4ac.Calculate (−9)2−4⋅6⋅(−5)=81+120=201.
Continue simplifying formula: Continue simplifying the quadratic formula with the values obtained. h=129±201.
Calculate two possible solutions: Calculate the two possible solutions for h. First solution: h=129+201. Second solution: h=129−201.
Round values to nearest hundredth: Round the values of h to the nearest hundredth, if necessary.First solution: h≈(9+14.18)/12≈23.18/12≈1.93.Second solution: h≈(9−14.18)/12≈−5.18/12≈−0.43.
