Answer:
(6 +31)(6 - 31) = -925
(4 -51)(4+51) = -2585
(-3 +81)(-3-81) = -6552
Step-by-step explanation:
(6 + 31)(6 - 31)
6 + 31 = 37
6 - 31 = -25
(37)(-25)
37 * -25 = -925
(6 +31)(6 - 31) = -925
(4 -51)(4+51)
4 - 51 = -47
4 + 51 = 55
(-47)(55)
-47 * 55 = -2585
(4 -51)(4+51) = -2585
(-3 +81)(-3-81)
-3 + 81 = 78
-3 - 81 = -84
(78)(-84)
78 * -84 = -6552
(-3 +81)(-3-81) = -6552
