Question

if a=x² B= 4x²+x-1 C = x+1 then find (a-b) (a-c)​

Answer 1

Answer:

-3x^4+2x^3-x^2-2x+1

Step-by-step explanation:

given that; a=x²  B= 4x²+x-1  C = x+1 then find (a-b) (a-c)​

Therefore; (a-b)=-3x^2-x+1

                  (a-c)=x^2-x+1

therefore; we get -3x^4+3x^3-3x^2-x^3+x^2-x+x^2-x+1

THEREFORE ANSWER=(A-B)(A-C)=-3x^4+2x^3-x^2-2x+1
