Answer:
Step-by-step explanation:
We have the two functions:
And we want to find:
This is equivalent to:
Therefore, we will have:
By substitution:
Simplify. Square and distribute:
Rearrange:
Combine like terms:
Answer:
a² + 2ab + b²
Explanation:
⇒ (a + b)²
⇒ (a + b)(a + b)
[apply distributive method: (a + b) (c + d) = ac + ad + bc + bd]
⇒ a² + ab + ab + b²
⇒ a² + 2ab + b²
