Answer:
Step-by-step explanation:
first take 4a squared and plug in, if a is equal to two then you would get 4(2)squared. First multiply the two times two. 4. you would now be elft with 4(4), multiply these and get 16. Now we shall solve for -4ab. 4(2)(5). First multiply two times five, so ten, then multiply four times ten. 40! your equation currently would look like- 16-40+b squared. For b squared you would plug in first so five to the second power. multiply five times five and get 25. now solve the equation, 16-40+25. the answer is 1
the asnwer is b) 1
