Quadratic Formula Explanation: The quadratic formula is used to solve equations of the form ax2+bx+c=0. The formula is given by x=2a−b±b2−4ac. For the equation w2+2w+1=0, we have a=1, b=2, and c=1.
Calculate Discriminant: First, we calculate the discriminant, which is the part under the square root in the quadratic formula: b2−4ac. For our equation, the discriminant is (2)2−4(1)(1)=4−4=0.
Apply Quadratic Formula: Since the discriminant is 0, this means that there is only one real solution to the equation, because the square root of 0 is 0. We can proceed to apply the quadratic formula with the discriminant.
Solve for w: Using the quadratic formula with our values of a, b, and c, we get w=2⋅1−2±0. This simplifies to w=2−2±0.
Solve for w: Using the quadratic formula with our values of a, b, and c, we get w=2⋅1−2±0. This simplifies to w=2−2±0. Simplifying further, we find that w=2−2, which gives us w=−1.
