Q. Solve for q.q2−14q+13=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.q = ____
Identify Coefficients: Identify the coefficients in the quadratic equationq2−14q+13=0. Here, a=1, b=−14, and c=13. We need to find two numbers that multiply to ac (which is 13) and add up to b (which is −14).
Find Multiplying Numbers: Find two numbers that multiply to 13 and add up to −14. The numbers −1 and −13 satisfy these conditions because −1×−13=13 and −1+−13=−14.
Write Original Equation: Write the original equation by splitting the middle term using the two numbers found in Step 2.q2−14q+13=q2−q−13q+13
Factor by Grouping: Factor by grouping. Group the terms to factor out the common factors.(q2−q)−(13q−13)= q(q−1)−13(q−1)
Factor out Common Factor: Factor out the common binomial factor (q−1).(q−1)(q−13)=0
Set Factors Equal: Set each factor equal to zero and solve for q.q−1=0 or q−13=0If q−1=0, then q=1.If q−13=0, then q=13.
