Question

if 1 is a zero of the polynomial p(a)=x²a²-3xa+3x-1, find the value of x​

Answer 1

Answer:

x=-1,and x=1

Step-by-step explanation:

Here, 1 is the zero of the polynomial p(a).So,putting the value of a=1.

Now, P(a)=x²a²-3xa+3x-1

P(1)=x²(1)²-3x×1+3x-1=0

=x²-3x+3x-1 =0

=x²-1 =0

=x²-(1)²=0

=(x+1)(x-1)=0

So,x=-1 or x=1
