Q. Solve for q.q2−6q−7=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 Equation: Identify the quadratic equation to be solved.The given quadratic equation is q2−6q−7=0. We need to find values of q that satisfy this equation.
Factor Equation: Factor the quadratic equation.We need to find two numbers that multiply to −7 and add up to −6. The numbers −7 and 1 satisfy these conditions because −7×1=−7 and −7+1=−6.So we can write the equation as (q−7)(q+1)=0.
Solve Using Property: Solve for q using the zero product property.If (q−7)(q+1)=0, then either q−7=0 or q+1=0.For q−7=0:q=7For q+1=0:q=−1We have found the two solutions for q.
