Question

evaluate the following

6a - 562 + 2c2 - 3a²bc
if a = 1, b = 2, c= -1 ​

Answer 1

Answer:

$6a - 562 + 2 {c}^{2} - 3 {a}^{2}bc$

$(6 \times 1) - 562 + (2 \times { - 1}^{2}) - (3 \times {1}^{2} \times 2 \times - 1)$

$6 - 562 + 2 + 6$

$- 548$

Answer 2

Answer:

6a–562 + 2c² – 3a²bc

(6 x 1) –562 + (2 x -1²) –(3 x 1² x 2 x –1)

6 – 562 + 2 + 6

–548
