Q. Solve using the quadratic formula.6s2−2s−8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.s=_____ or s=_____
Identify values of a, b, c: Identify the values of a, b, and c in the quadratic equation6s2−2s−8=0. The quadratic equation is in the form as2+bs+c=0. Comparing this with our equation, we get: a=6b=−2b0
Substitute into quadratic formula: Substitute the values of a, b, and c into the quadratic formula s=2a−b±b2−4ac. Substitute a=6, b=−2, and c=−8 into the formula. s=2⋅6−(−2)±(−2)2−4⋅6⋅(−8)
Simplify expression and constants: Simplify the expression under the square root and the constants outside the square root.Calculate (−2)2, 4×6×(−8), and 2×6.(−2)2=44×6×(−8)=−1922×6=12Now substitute these values back into the formula.s=122±4+192
Simplify expression inside square root: Simplify the expression inside the square root and then the square root itself.Calculate 4+192.4+192=196Now take the square root of 196.196=14Now substitute this value back into the formula.s=(2±14)/12
Calculate two possible solutions: Calculate the two possible solutions for s.First solution:s=(2+14)/12s=16/12s=4/3Second solution:s=(2−14)/12s=−12/12s=−1
Write final answers: Simplify the fractions and write the final answers.The first solution 34 is already in its simplest form.The second solution −1 is an integer.So the final answers are:s=34 or s=−1
