Verify that a =(b+c)(a + b)+(a + c) for each of the following values of a, b and c

(a) a =(b+c)(a + b)+(a + c)
12= (-4+2)(12-4)+(12+2)
12= -2×8 + 14
12= -16 +14
12 not equal to -2 not verified
(b) a =(b+c)(a + b)+(a + c)
-10=(1+1)(-10+1)+(-10+1)
-10= 2×-9+ (-9)
-10= -18 -9
10 is not equal to -27 not verified
