Q. Solve using the quadratic formula.g2−6g−5=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 equationg2−6g−5=0. The standard form of a quadratic equation is ax2+bx+c=0. Comparing this with our equation, we get: a=1b=−6c=−5
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. Here, a=1, b=−6, and c=−5.
Calculate discriminant: Calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac.Discriminant = (−6)2−4(1)(−5)Discriminant = 36+20Discriminant = 56
Substitute discriminant into formula: Substitute the discriminant back into the quadratic formula and simplify.g=2×1−(−6)±56g=26±56Since 56 can be simplified to 4×14 which is 2×14, we get:g=26±2×14
Simplify expression: Simplify the expression by dividing both terms in the numerator by 2.g=(3±14)We now have two possible solutions for g.
Round values: Round the values of g to the nearest hundredth, if necessary.g=3+14 or g=3−14g≈3+3.74 or g≈3−3.74g≈6.74 or g≈−0.74
