Q. Solve for j.j2+8j+15=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.j=____
Identify Quadratic Equation: Identify the quadratic equation to be solved.The given quadratic equation is j2+8j+15=0. We need to find values of j that satisfy this equation.
Factor Equation: Factor the quadratic equation.We need to find two numbers that multiply to 15 and add up to 8. The numbers 3 and 5 satisfy these conditions because 3×5=15 and 3+5=8.
Write Factored Form: Write the factored form of the equation.The equation can be factored as (j+3)(j+5)=0.
Solve Using Zero Product Property: Solve for j using the zero product property.If (j+3)(j+5)=0, then either j+3=0 or j+5=0.First, solve j+3=0:j+3−3=0−3j=−3Next, solve j+5=0:j+5−5=0−5j=−5
Write Solutions: Write the solutions for the equation j2+8j+15=0. The solutions are j=−3 and j=−5.
