QuestionFactor the quadratic function and find the value of that fits: .
Studdy Solution
STEP 1
Assumptions1. The given quadratic function is
. We are required to solve this function by factoring3. One root of the function is given as
4. We need to find the other root of the function
STEP 2
The general form of a quadratic function is . The roots of a quadratic function can be found by factoring the function into the form , where p and q are the roots of the function.
STEP 3
Given that one root is , we can write the function in the form .
STEP 4
We can find the value of q by comparing the given function with the factored form .
STEP 5
Expanding the factored form, we get . This should be equal to the given function .
STEP 6
Comparing the coefficients, we have1. Coefficient of
2. Coefficient of :
3. Constant term
STEP 7
olving the equation for q, we get .
STEP 8
Substitute into the equation to check if it holds true.
STEP 9
Calculate the left-hand side of the equation .
STEP 10
Since the left-hand side equals the right-hand side, is indeed the other root of the function.
