Question

А^+(5a-b)^ Помогите пожалуйста

Answer 1

${a}^{2} + {(5 a - b)}^{2} = {a}^{2} + {25a}^{2} - 10ab + {b}^{2} = {26a}^{2} - 10ab + {b}^{2}$

Answer 2

Calculation of (5a-b)^2

To calculate the expression (5a-b)^2, we can use the formula for squaring a binomial, which is (a-b)^2 = a^2 - 2ab + b^2. In this case, we have (5a-b)^2, so we can substitute 5a for a and b for b in the formula.

Therefore, (5a-b)^2 = (5a)^2 - 2(5a)(b) + b^2.

Simplifying further, we get:

(5a-b)^2 = 25a^2 - 10ab + b^2.

So, the expression (5a-b)^2 simplifies to 25a^2 - 10ab + b^2.
