2a +2b​

Answer 1

Answer:

it question is not appropriate check it

Answer 2

Step-by-step explanation:

${x}^{2} - 25 = 0 \\ {a}^{2} - {b}^{2} = (a - b)(a + b) \\ {x}^{2} - {5}^{2} = (x - 5)(x + 5) \\ x - 5 = 0 \: \: \: \: \: \: \: x + 5 = 0 \\ x = 5 \: \: \: \: \: \: \: \: x = - 5 \\ \alpha = 5 \: \: \: \: \beta = - 5 \\ \\ 2 \alpha + 2\beta \\ = 2(5) + 2( - 5) \\ = 10 - 10 \\ = 0$
