Question

if f(x)=x(x+1)(2x+1)then find f(x)-f(x-1)

Answer 1

Answer:

x²(4x^4-x²-4x²-1)

Step-by-step explanation:

f(x)= x(x+1)(2x+1)

then

f(x-1) = (x-1)((x-1)+1)(2(x-1)+1)

= (x-1)x(2x-1) = x(x-1)(2x-1)

=⟩ f(x) - f(x-1) = x(x+1)(2x+1)*x(x-1)(2x-1)

= x²(x+1)(x-1)(2x+1)(2x-1)

= x²(x²-1)((2x)² -1)

= x²(x²-1)(4x²-1)

= (x^4-x²)(4x²-1)

= 4x^6 - x^4 -4x^4 -x²

or, = x²(4x^4-x²-4x²-1)
