Q. Solve for d.d2+24d−25=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 quadratic equation: Identify the quadratic equation to solve.The given quadratic equation is d2+24d−25=0. We need to find values of d that satisfy this equation.
Factor quadratic equation: Factor the quadratic equation.We need to find two numbers that multiply to −25 and add up to 24. The numbers 25 and −1 satisfy these conditions because 25×(−1)=−25 and 25+(−1)=24.So, we can write the equation as (d+25)(d−1)=0.
Solve for d: Solve for d using the zero product property.If (d+25)(d−1)=0, then either d+25=0 or d−1=0.For d+25=0:Subtract 25 from both sides to solve for d.d+25−25=0−25d=−25For d−1=0:Add 1 to both sides to solve for d.d−1+1=0+1d+25=00
