Question

What should be subtracted from the polynomial of p(x)=x2-3 ax +3 a – 7 so that, (x + 2) is a
factor of the polynomial p(x) and hence also find the value of a​

Answer 1

Step-by-step explanation:

Since x+1 is a factor of the polynomial p(x)=x

2

−3ax+3a−7

Therefore, by Factor theorem p(−1)=0

⇒(−1)

2

−3a(−1)+3a−7=0

⇒1+3a+3a−7=0⇒a=1

Answer 2

Answer:

a=1/3

x²-x-6 should be subtracted from the p(x)..

Step-by-step explanation:

This is the answer for this question...
