Question

3(m-1)^2+(m+2)(m^2-2m+4)-(m+1)^3 где m=-3/1

Answer 1

Відповідь:

Розкриваємо дужки:

3m^2 – 6m + 3 + m^3 + 2m^2 – 4m + 4m + 8 – m^3 – m^2 + m^2 + m – m – 1 = 3m^2 + 10

Answer 2

To evaluate the expression, you need to substitute the value of "m" into the given expression and then perform the calculations. Let's go step by step:

Step 1: Substitute the value of "m" into the expression. m = -3/1 (which is equal to -3)

Step 2: Evaluate the expression using the given value of "m."

3(m - 1)^2 + (m + 2)(m^2 - 2m + 4) - (m + 1)^3 = 3(-3 - 1)^2 + (-3 + 2)((-3)^2 - 2(-3) + 4) - (-3 + 1)^3 = 3(-4)^2 + (-1)(9 + 6 + 4) - (-2)^3 = 3(16) - 19 + 8 = 48 - 19 + 8 = 29 + 8 = 37

Therefore, when m = -3/1, the expression evaluates to 37.
