Q. Solve using the quadratic formula.4g2−4g−3=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.g=_____ or g=_____
Identify values of a, b, c: Identify the values of a, b, and c in the quadratic equation4g2−4g−3=0. The quadratic equation is in the form ag2+bg+c=0, so by comparison: a=4b=−4b0
Substitute values into formula: Substitute the values of a, b, and c into the quadratic formula to find g. The quadratic formula is g=2a−b±b2−4ac. Substituting the values we get: g=2⋅4−(−4)±(−4)2−4⋅4⋅(−3)
Simplify discriminant: Simplify the expression under the square root (the discriminant). (−4)2−4⋅4⋅(−3)=16+48=64
Continue simplifying formula: Continue simplifying the quadratic formula with the calculated discriminant. g=84±64
Solve for possible values: Solve for the two possible values of g.g=84+8 or g=84−8g=812 or g=8−4
Simplify final answers: Simplify the fractions to get the final answers.g=812 simplifies to g=23 or g=1.5g=8−4 simplifies to g=2−1 or g=−0.5
