Question

expand and combine the like terms (2-3d^3)^2

Answer 1

Answer:

Option 4. $4-12d^3+9d^6$

Step-by-step explanation:

$(2-3d^3)^2 = (2-3d^3)(2-3d^3)$

$= 4-6d^3-6d^3+9d^6$

$=4-12d^3+9d^6$

Note: Don't just square each term inside the brackets as it will give you an incorrect result. Write it out as a product to avoid making this mistake if you are not familiar with expanding binomial products.

Hope this helps :)
