Answer:
-35
Step-by-step explanation:
[tex]-4a^{2} +2a-1[/tex]
Now we substitute and simplify:
[tex]-4(3)^{2} +2(3)-1[/tex]
[tex]-4(9)+6-1[/tex]
[tex]-36+6-1[/tex]
[tex]-36+5[/tex]
-35 is our final answer
Answer: -31
Step-by-step explanation:
4(3)^2+2(3)−1
Calculate 3 to the power of 2 and get 9.
−4×9+2×3−1
Multiply −4 and 9 to get −36.
−36+2×3−1
Multiply 2 and 3 to get 6.
−36+6−1
Add −36 and 6 to get −30.
−30−1
Subtract 1 from −30 to get −31.
−31
