Answer 2

Answer:

14

Step-by-step explanation:

given the equation = 2a^2 +2b^2-2c^2

given that the values a=2 b=-2 c=1

respectively

by substuting the values of a,b and c in the equation

we get,

=2×(2^2) + 2×(-2^2) - 2×(1^2)

=(2× 4) + (2×4) - (2×1)

=8+8-2

=16-2

=14

there fore the value of the equation is14
