Question

(6-m)²-m(3+m) при m=2/15

Answer 1

Ответ:

34

Объяснение:

(6–m)²–m(3+m)= 36–12m+m²–3m–m²= 36–15m

при m=2/15

36–(15*(2/15))=36–2=34

Answer 2

To evaluate the expression (6-m)² - m(3+m) when m = 2/15, we'll substitute the value of m into the expression and then perform the calculations step-by-step:

Step 1: Substitute m = 2/15 into the expression: (6 - m)² - m(3 + m)

Step 2: Replace m with 2/15 in each term: (6 - 2/15)² - (2/15)(3 + 2/15)

Step 3: Perform calculations within parentheses first: (89/15)² - (2/15)(49/15)

Step 4: Square the first term: (7921/225) - (2/15)(49/15)

Step 5: Multiply the second term: (7921/225) - (98/225)

Step 6: Subtract the second term from the first: (7921/225) - (98/225) = (7921 - 98)/225 = 7823/225

So, the result of the expression (6-m)² - m(3+m) when m = 2/15 is 7823/225.
