If a = 1 and b = -2, then (2a^2 + b)(w + y) + (a + b)(w - y) =	Choices:
A) 0
B) 2x
C) y - w
D) x - y
E) x + y
Putting A=1 and B = -2 =&gt; 2A^2-B=0 ; so the first part of the term is zero   with second term =&gt; (1-2) *(w+y)=y-w =&gt; Smash y - w
<result>C</result>
If a = 1 and b = -2, then (2a^2 + b)(w + y) + (a + b)(w - y) =
