Q. Solve using the quadratic formula.9g2+g−5=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.g= _____ or g= _____
Quadratic Formula: The quadratic formula is given by g=2a−b±b2−4ac, where a, b, and c are the coefficients from the quadratic equation in the form ax2+bx+c=0. For the equation 9g2+g−5=0, a=9, b=1, and c=−5.
Calculate Discriminant: First, calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. Here, it is 12−4(9)(−5).
Discriminant Calculation: Perform the calculation: 1−4(9)(−5)=1+180=181.
Use Quadratic Formula: Now, insert the values of a, b, and the discriminant into the quadratic formula to find the two possible values for g.g=2⋅9−1±181
Simplify Formula: Simplify the formula by dividing −1 and 181 by 18.g=(18−1)±(18181)
Calculate Decimal Values: Since 181 cannot be simplified to an integer or a simple fraction, and the problem asks for decimals if necessary, we will calculate the decimal values of g rounded to the nearest hundredth.
Calculate Solutions: Calculate the two possible solutions for g using a calculator:g=18−1+181≈18−1+13.45≈1812.45≈0.69g=18−1−181≈18−1−13.45≈18−14.45≈−0.80
