Question

(a + 8) ² - 2 (a-3x)​

Answer 1

=a^2+16а+64-2а+6х=а^2+14а+64+6x

Answer 2

To simplify the expression (a + 8)² - 2(a - 3x), we can use the formula for the square of a binomial, which is:

(a + b)² = a² + 2ab + b²

Using this formula, we can expand (a + 8)² as:

(a + 8)² = a² + 2(a)(8) + 8² = a² + 16a + 64

Now let's simplify the second term, which is 2(a - 3x):

2(a - 3x) = 2a - 6x

Putting it all together, we can rewrite the original expression as:

(a + 8)² - 2(a - 3x) = (a² + 16a + 64) - (2a - 6x)

Simplifying further by distributing the negative sign:

= a² + 16a + 64 - 2a + 6x

= a² + 14a + 6x + 64

So the simplified form of the expression is a² + 14a + 6x + 64.
