Answer: The solutions for are and .
Step-by-step solution
Step 1: Identify coefficients
The given equation is . This is a quadratic equation in the standard form . By comparing the given equation with the standard form, we can identify the coefficients , , and .
Step 2: Apply the quadratic formula
Now that we have the values of , , and , we can use the quadratic formula to find the values of . The quadratic formula provides the solutions for any quadratic equation.
Step 3: Substitute values into the formula
Substitute the identified values , , and into the quadratic formula. Be careful with the signs, especially for the term .
Step 4: Simplify the expression
First, calculate the term inside the square root, which is the discriminant . Then, simplify the square root and the denominator.
Step 5: Calculate the two possible values for x
The sign in the quadratic formula indicates that there are two possible solutions for . Calculate each solution separately, one using the plus sign and the other using the minus sign.
Step 6: Final solutions
Perform the final division for both expressions to get the two solutions for . These are the roots of the quadratic equation.
