Question

if A=x2+2x+1 and B=x2-2x+1 then 2A-B=?? Please answer fast

Answer 1

Step-by-step explanation:

first 2A =X2+2x+1 × 2

so,2a=x4+4x+2

now ,2a-b=x4+4x+2(-)x2-2x+1 =

so, x4+4x+2

(-) X2-2x+1

x6+2x+1

so, therefour 2a+b

= x6+2x+1

Answer 2

Answer:

A=x²+2x+1

B=x²-2x+1

then,2A-B=2(x²+2x+1)-(x²-2x+1)

=2x²+4x+2-x²+2x-1

=x²+6x+1
