Question

If 1 is zero of the polynomial p( x)=ax²-3(a-1)x-1,then find the value of a

Answer 1

Answer:

a=1

Step-by-step explanation:

If 1 is a zero of the polynomial ax2-3(a-1)x-1, then find the value of a. Solution : Since 1 is a zero of ax2-3(a-1)x-1, we have a-3(a-1)-1=0. ∴A-3a+3-1=0⇒2a=2⇒a=1.
