Evaluate (1005)*2-995×994 using a^2-b^2=(a+b)(a-b)

1.	Evaluate (1005)*2-995×994 using a^2-b^2=(a+b)(a-b)
Answer» ${1005}^{2} - (994 + 1) \times 994 \\ = {1005}^{2} - {944}^{2} + 944 \\ = (1005 - 944)(1005 + 944) + 944 \\ = 61 \times 1949 + 944 \\ = 118889 + 1949 \\ = 119833$ HOPE THIS HELPS YOU PLZ MARK ME AS BRAINLIEST ✌✌

Answer»

${1005}^{2} - (994 + 1) \times 994 \\ = {1005}^{2} - {944}^{2} + 944 \\ = (1005 - 944)(1005 + 944) + 944 \\ = 61 \times 1949 + 944 \\ = 118889 + 1949 \\ = 119833$
