Question 1

Evaluate the expression when a = 1/4 and b = 6 16a^2 - 4b

Question 2

$\huge\text{Hey there!}$

$\mathsf{16a^2 - 4b}$

$\mathsf{= 16((1)/(4))^2 - 4(6)}$

$\mathsf{= 16((1)/(4) * (1)/(4)) - 4(6)}$

$\mathsf{= 16* (1(1))/(4(4)) - 4(6)}$

$\mathsf{= 16((1)/(16)) - 4(6)}$

$\mathsf{= (16)/(1)((1)/(16)) - 4(6)}$

$\mathsf{= (16(1))/(1(16)) - 4(6)}$

$\mathsf{= (16)/(1) - (4(6))/(1)}$

$\mathsf{= 1 - 4(6)}$

$\mathsf{= 1 - 24}$

$\mathsf{= -23}$

$\huge\text{Therefore, your answer should be: }$

$\huge\boxed{\mathsf{-23}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
