Question

Select all the correct locations on the table.Which expressions are accurately described?3(7x² - 4)25y2-16(4x + 5)²(2y + 1)(y + 6)the product of 3 and the difference of 7times x squared and 4the square of the difference of 25 timesy and 16the sum of 4 times x squared and 5the product of the sum of 2 times y and1 and the sum of y and 6

Answer 1

We have:

- the product of 3 and the difference of 7 times x squared and 4 is:

`3(7x^2-4)`

Correct.

- the square of the difference of 25 times y and 16 is:

`(25y-16)^2`

So, not correct.

- the sum of 4 times x squared and 5 is:

`4x^2+5`

So, not correct.

- the product of the sum of 2 times y and 1 and the sum of y and 6 is:

`(2y+1)(y+6)`

Correct.

Answer:

The first one and the fourth one
