Question

3(a2+2)2-22(a2+2a)2+40

Answer 1

Answer:

$\Huge \boxed{-164a+52}$

Step-by-step explanation:

$\textnormal{To solve this problem, first, you have to isolate by the "a" on one side of the equation.}$

$\large \boxed{\textnormal{To use distributive property of \boxed{a(b+c)=ab+ac}}}}.$

$\large {\textnormal{Solve.}}$

$\displaystyle 3(a*2+2)*2=6(2a+2)$

$\displaystyle 22(a*2+2a)*2=176a$

$\displaystyle 6(2a+2)-176a+40$

$\large\textnormal{Solve with expanding the form of the distributive property.}$

$\displaystyle 6(a*2+2)=12a+12$

$\large\textnormal{Then, subtract numbers from left to right.}$

$\displaystyle 176a+40-12a+2=\boxed{-164a+52}$

$\large\boxed{\textnormal{As a result, the correct answer is \boxed{-164a+52}}}}$
