Q. Solve using the quadratic formula.8s2−s−8=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.s=_____ or s=_____
Identify coefficients: Identify the coefficients a, b, and c in the quadratic equation8s2−s−8=0.a=8, b=−1, c=−8
Write quadratic formula: Write down the quadratic formula: s=2a−b±b2−4ac.
Substitute values: Substitute the values of a, b, and c into the quadratic formula.s=2⋅8−(−1)±(−1)2−4⋅8⋅(−8)
Calculate discriminant: Simplify the equation by calculating the discriminant (the part under the square root). Discriminant = (−1)2−4⋅8⋅(−8)=1+256=257
Insert discriminant: Insert the discriminant back into the formula and simplify. s=161±257
Calculate solutions: Calculate the two possible solutions for s.s=161+257 or s=161−257
Round values: Round the values of s to the nearest hundredth, if necessary.s≈(1+16.03)/16 or s≈(1−16.03)/16s≈17.03/16 or s≈−15.03/16s≈1.06 or s≈−0.94
