Question

expand 3/2 X+1 whole cube​

Answer 1

Given: The equation ( (3x/2) + 1)^3

To find: Write it in expanded form.

Solution:

• Now we have given ( (3x/2) + 1)^3

• We know the formula:

                (a + b)^3 = a^3 + b^3 + 3ab(a+b)

• So using this formula, we get:

                ( (3x/2) + 1)^3 = (3x/2)^3 + 1^3 + 3(3x/2)(1)((3x/2) + 1)

                ( (3x/2) + 1)^3 = 27x^3 / 8 + 1 + 27x^2 /4 + 9x/2

                ( (3x/2) + 1)^3 = 27x^3 / 8 + 27x^2 /4 + 9x/2 + 1

Answer:

             So the expanded form is 27x^3 / 8 + 27x^2 /4 + 9x/2 + 1

( (3x/2) + 1)^3 = 27x^3 / 8 + 27x^2 /4 + 9x/2 + 1

Answer:

So the expanded form is 27x^3 / 8 + 27x^2 /4 + 9x/2 + 1
