Q:
Subtract these polynomials. (3x2 + 2x + 4) - (x2 + 2x + 1) = A. 2x2 + 5 B. 2x2 + 4x + 3 C. 2x2 + 3 D. 2x2 + 4x + 5
Accepted Solution
A:
=(3x2 + 2x + 4) - (x2 + 2x + 1)
Combine like terms
=(3x2-x2)+(2x-2x)+(4-1)
=2x2+0+3
The 2x terms cancel each other to 0
=2x2+3
C) 2x2+3 is the answer.
Hope this helps! :)
