Q. Solve using the quadratic formula.9g2−4g−1=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.g=_____ or g=_____
Identify values: Identify the values of a, b, and c in the quadratic equation9g2−4g−1=0. Comparing the equation with the standard form ax2+bx+c=0, we find: a=9b=−4c=−1
Substitute in formula: Substitute the values of a, b, and c into the quadratic formula g=2a−b±b2−4ac.g=2⋅9−(−4)±(−4)2−4⋅9⋅(−1)
Simplify expression: Simplify the expression under the square root and the constants outside the square root. g=184±16+36g=184±52
Simplify square root: Simplify the square root. 52 can be simplified to 213 because 52=4×13. g=184±213
Divide by 2: Simplify the expression by dividing all terms by 2.g=92±13
Identify possible values: Identify the two possible values for g.g=92+13 or g=92−13
Round to nearest hundredth: Round the values of g to the nearest hundredth, if necessary.g≈9(2+3.61) or g≈9(2−3.61)g≈95.61 or g≈9−1.61g≈0.62 or g≈−0.18
