Hey there!!
The given equation : 2b² - 4a + 4a²
Where, a = 3 and b = -8
Now, we will have to substitute these values in the equation given above
2 ( - 8 )² - 4 ( 3 ) + 4 ( 3 ) ²
( -8 )² = 64
Because -8 × -8 = 64 . As ( - ) × ( - ) = ( + )
negative × negative = positive
Now, moving on
2 ( 64 ) - 4 ( 3 ) + 4 ( 9 )
128 - 12 + 36
116 + 36
The required answer is 152.
Hope my answer helps!!
