Answer 2

Answer:

Question:-

If a = 3, b = 2 and c = -1, find the value of 2a²b - 8bc + c²

Solution:-

Put the value of a is 3 , b is 2 and c is (-1)

$= 2 {a}^{2} b - 8bc + {c}^{2}$

$= 2 \times 3 \times 3 \times 2 - 8 \times 2 \times ( - 1) + ( - 1) \times ( - 1)$

$= 36 - ( - 16) + 1$

$= 36 + 16 + 1$

$= 53$
