Question

expand following cube 3by2x+1​

Answer 1

Answer:

8xcube+12xsquare+6x+1

Answer 2

Step-by-step explanation:

• We need to expand the given problem (3/2 x + 1)^3
• We have the identity (a + b)^3 = a^3 + b^3 + 3ab (a + b)
• So here a = 3/2 x and b = 1
• Substituting the values of a and b we get
•        So (3/2 + 1)^3 = (3/2 x)^3 + 1^3 + 3(3/2 x)(1) (3/2 x + 1)
•                                = 27/8 x^3 + 1 + 9/2 x  (3/2 x + 1)
•                                = 27/8 x^3 + 1 + 9/2 x (3/2 x) + 9/2 x
•                               = 27/8 x^3 + 27/4 x^2 + 9/2 x + 1
