Q. Solve using the quadratic formula.9g2+2g−6=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.g=_____ or g=_____
Identify coefficients: Identify the coefficients of the quadratic equation9g2+2g−6=0. The standard form of a quadratic equation is ax2+bx+c=0. Here, a=9, b=2, and c=−6.
Write formula: Write down the quadratic formula.The quadratic formula is given by w=2a−b±b2−4ac.
Substitute values: Substitute the values of a, b, and c into the quadratic formula.g=2⋅9−2±22−4⋅9⋅(−6)
Simplify discriminant: Simplify the expression under the square root (the discriminant). 22−4⋅9⋅(−6)=4+216=220
Simplify square root: Simplify the square root of 220.220 can be simplified to 255 because 220=4×55.
Substitute back: Substitute the simplified square root back into the formula. g=18−2±255
Divide by 2: Simplify the expression by dividing all terms by 2.g=9−1±55
Calculate solutions: Calculate the two possible solutions for g.g=9−1+55 or g=9−1−55
Round values: Round the values of g to the nearest hundredth, if required.g≈(−1+7.42)/9 or g≈(−1−7.42)/9g≈6.42/9 or g≈−8.42/9g≈0.71 or g≈−0.93
