Q. Solve for d. d2−10d−24=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas. d=____
Identify the quadratic equation: Identify the quadratic equation to be solved.The given quadratic equation is d2−10d−24=0. We need to find values of d that satisfy this equation.
Factor the quadratic equation: Factor the quadratic equation.We need to find two numbers that multiply to −24 and add up to −10. The numbers −12 and 2 satisfy these conditions because −12×2=−24 and −12+2=−10.
Write factored form: Write the factored form of the equation.Using the numbers found in Step 2, we can write the factored form of the equation as (d−12)(d+2)=0.
Solve using zero product property: Solve for d using the zero product property.If (d−12)(d+2)=0, then either d−12=0 or d+2=0.First, solve d−12=0:Add 12 to both sides to get d=12.Second, solve d+2=0:Subtract 2 from both sides to get d=−2.
