2a+ac+ba+bc математика))

Answer 2

To expand the given expression $(a+b)(a+c)$, you can use the distributive property of multiplication over addition, which states that $a(b+c) = ab + ac$. Here's the step-by-step expansion:

$(a+b)(a+c) = a(a+c) + b(a+c)$

Now, apply the distributive property to both terms:

$= a \cdot a + a \cdot c + b \cdot a + b \cdot c$

Finally, simplify the terms:

$= a^2 + ac + ba + bc$

Since multiplication is commutative, we can rearrange the terms:

$= a^2 + ba + ac + bc$

So, the expanded form of $(a+b)(a+c)$ is $a^2 + ba + ac + bc$.
