Question

Help! I do not understand a single thing lol I’m sorry<3

Answer 1

${4c}^{2} d {}^{2} - 8c {}^{4} d + 16c - 2d \\ the \: value \: of \: c = - 1 \\ the \: value \: of \: d \: = 4 \\ 4 \times {( - 1)}^{2} \times {4}^{2} - 8 \times {( - 1)}^{4} \times 4 + 16 \times ( - 1) - 2 \times 4 \\ 4 \times 16 - 8 \times 4 - 16 - 8 \\ 64 - 32 - 16 - 8 \\ 8$

Sorry if I am incorrect.....

Answer 2

= 8

step-by-step explanation:

evaluate

-8c⁴ d +4c² d² + 16c - 2d

when c =-1 ,d=4

=8

hope it helps!
