Q. Solve using the quadratic formula.4f2−6f+1=0Write your answers as integers, proper or improper fractions in simplest form, or decimals rounded to the nearest hundredth.f=_____ or f=_____
Identify values: Identify the values of a, b, and c in the quadratic equation4f2−6f+1=0. The quadratic equation is in the form af2+bf+c=0, so by comparison: a=4b=−6c=1
Substitute values: Substitute the values of a, b, and c into the quadratic formula.The quadratic formula is f=2a−b±b2−4ac.Substituting the values we get:f=2⋅4−(−6)±(−6)2−4⋅4⋅1
Simplify equation: Simplify the equation.f=86±36−16f=86±20Since 20 simplifies to 25, we can write:f=86±25
Simplify fractions: Simplify the fractions.We can divide the numerator and the denominator by 2 to simplify the expression:f=43±5
Calculate values: Calculate the two possible values for f.f=43+5 or f=43−5Now we can approximate 5 to the nearest hundredth:5≈2.24f≈43+2.24 or f≈43−2.24f≈45.24 or f≈40.76f≈1.31 or f=43+50
