Solve the quadratic equation using the quadratic formula .
Answer: The solutions to the quadratic equation are and .
Step-by-step solution
Step 1: Identify coefficients
First, we compare the given quadratic equation with the standard form of a quadratic equation, . By comparing the coefficients, we identify the values for , , and .
Step 2: Substitute into the quadratic formula
Now, we substitute the identified values of , , and into the quadratic formula . This sets up the equation for solving .
Step 3: Simplify the expression under the square root
We simplify the expression under the square root, which is the discriminant. First, we calculate and . Then, we subtract these values to get .
Step 4: Calculate the square root
The square root of is . We replace with in the formula.
Step 5: Find the two possible values for x
Finally, we calculate the two possible values for . For the first value, we use the plus sign: . For the second value, we use the minus sign: .
