Question

A2 - b2 * 2a + 26 ____ _____ = (a+b)2 5a-5b

Answer 1

Вот решение, надеюсь всё видно

Answer 2

The given expression is:

A2 - b2 * 2a + 26 ____ _____ = (a+b)2 5a-5b

To solve for the missing values, we can use the identity:

(a+b)2 = a2 + 2ab + b2

Let's simplify the left-hand side of the given expression first:

A2 - b2 * 2a + 26

= A2 - 2ab + b2 + (2ab - b2 + 26)

= (A - b)2 + (2ab - b2 + 26)

Comparing with (a+b)2, we can see that:

A - b = a + b --> A = 2b + a

2ab - b2 + 26 = 5a - 5b

Multiplying both sides by -1 and rearranging, we get:

b2 - 2ab + 5b - 5a + 26 = 0

Now, substituting A = 2b + a, we get:

(2b + a)2 - b2 * 2a + 26 _____ _____ = (a+b)2 5a-5b

= (4b2 + 4ab + a2) - 2ab + 26 _____ _____ = (a+b)2 5a-5b

= 4b2 + 2ab + a2 + 26 _____ _____ = (a+b)2 5a-5b

= (a+b)2 + 26 _____ _____ = (a+b)2 5a-5b

Comparing the two sides, we can see that:

Missing value 1: 26 Missing value 2: 5a - 5b
