Q. (t+38)(t+b)=0In the given equation, b is a constant. If −38 and 313 are solutions to the equation, then what is the value of b?
Identify roots and factors: Identify the roots of the equation and relate them to the factors.Given roots: t=−38 and t=−313.The equation can be factored as (t+38)(t+b)=0.Thus, one factor is t+38, and the other is t+b.
Match roots to factors: Match the roots to the factors.Since t+38=0 when t=−38, the other root, t=−313, must satisfy t+b=0.So, set t+b=0 and substitute t=−313:−313+b=0.
Solve for b: Solve for b.−313+b=0b=313.
