Q. Solve for f.f2+12f−13=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.f=____
Identify the quadratic equation: Identify the quadratic equation.The given equation is f2+12f−13=0, which is a quadratic equation in the standard form af2+bf+c=0, where a=1, b=12, and c=−13.
Use the quadratic formula: Use the quadratic formula to solve for f. The quadratic formula is f=2a−b±b2−4ac. For our equation, a=1, b=12, and c=−13.
Calculate the discriminant: Calculate the discriminant.The discriminant is the part of the quadratic formula under the square root: b2−4ac. Let's calculate it:Discriminant = (12)2−4(1)(−13)=144+52=196.
Two real solutions: Since the discriminant is positive, there are two real solutions.Now we can find the two solutions using the quadratic formula:f=2×1−12±196.
Calculate the two solutions: Calculate the two solutions.First solution:f=2−12+196=2−12+14=22=1.Second solution:f=2−12−196=2−12−14=2−26=−13.
