1.	Write the following in roaster form: A={x:x^2-4x-5=0}
Answer» ANSWER: A={x : x²–4x–5=0} A={x : x²–5x+x–5=0} A={x : x(x–5)+1(x–5)=0} A={x : (x–5)+(x+1)=0} ⇒A={x : x = –1, 5} ∴ A={–1, 5} [in roster FORM]

Answer»

ANSWER:

A={x : x²–4x–5=0}

A={x : x²–5x+x–5=0}

A={x : x(x–5)+1(x–5)=0}

A={x : (x–5)+(x+1)=0}

⇒A={x : x = –1, 5}

∴ A={–1, 5} [in roster FORM]
