P H O T O M A T H it can solve the problem
Answer:
4(2a - 1) a²
(x−4a)(a+x)+x(3a−x)−(−2a)3
Use the distributive property to multiply x−4a by a+x and combine like terms.
−3xa+x2−4a2+x(3a−x)−(−2a)3
Use the distributive property to multiply x by 3a−x.
−3xa+x2−4a2+3xa−x2−(−2a)3
Combine −3xa and 3xa to get 0.
x2−4a2−x2−(−2a)3
Combine x2 and −x2 to get 0.
−4a2−(−2a)3
Expand (−2a)3.
−4a2−(−2)3a3
Calculate −2 to the power of 3 and get −8.
−4a2−(−8a3)
The opposite of −8a3 is 8a3.
−4a2+8a3
