Question

Replace the power with a product and then transform the product into a polynomial1. (3a-1)^2

Answer 1

We have

`\mleft(3a-1\mright)^2`

Write as a product is multiply the given binomial the number that we have in the power, in this case, the number of times is 2

The product is

`\mleft(3a-1\mright)^{}\mleft(3a-1\mright)^{}`

Then we need to simplify the product

`9a-3a-3a+1`

Then we sum like terms and we obtain the polynomial

`9a^2-6a+1`
