Rephrase the Problem: First, let's rephrase the problem into a "What are the values of x that satisfy the equation x2−6x=5?"
Move Terms: To solve the equation x2−6x=5, we need to move all terms to one side to set the equation equal to zero. We do this by subtracting 5 from both sides of the equation.x2−6x−5=0
Quadratic Formula: Now we have a quadratic equation in the standard form. We can attempt to factor it, or use the quadratic formula to find the values of x. The quadratic formula is x=2a−b±b2−4ac, where a, b, and c are the coefficients from the quadratic equation ax2+bx+c=0. In our case, a=1, b=−6, and c=−5.
Calculate Discriminant: Let's calculate the discriminant (b2−4ac) to see if factoring is possible or if we will have real solutions.Discriminant = (−6)2−4(1)(−5)=36+20=56Since the discriminant is positive, we have two real solutions, and it suggests that the equation might be factorable. However, since 56 is not a perfect square, factoring might be difficult or impossible. We will use the quadratic formula.
Apply Quadratic Formula: Applying the quadratic formula, we get:x=2⋅1−(−6)±56x=26±56x=26±4⋅14x=26±214
Simplify the Expression: We can simplify the expression by dividing both terms in the numerator by 2:x=3±(14)So we have two solutions for x.
