Q. Solve for t.t2+2t−8=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.t=____
Identify the quadratic equation: Identify the quadratic equation to be solved.We have the quadratic equation t2+2t−8=0.
Factor the quadratic equation: Factor the quadratic equation.We need to find two numbers that multiply to −8 and add up to 2. The numbers 4 and −2 satisfy these conditions because 4×−2=−8 and 4+(−2)=2.So we can write the equation as (t+4)(t−2)=0.
Solve for t: Solve for t using the zero product property.If (t+4)(t−2)=0, then either t+4=0 or t−2=0.For t+4=0:Subtract 4 from both sides to solve for t.t+4−4=0−4t=−4
Solve the second part: Solve the second part of the equation.For t−2=0:Add 2 to both sides to solve for t.t−2+2=0+2t=2
