8(x-1) - 3x(4-x) + 6 (x+2) - 3. How can I simplify this?

3 0

Use the distributive property. For the first set of parenthesis, multiply everything inside by 8. This gets you to 8x-8.

Next set: Everything inside by 3x: 12x+3x^2.

Next set: Everything inside by 6: 6x+12.

Put it all together: 8x-8-12x+3x^2+6x+12-3.

Combine like terms: 2x+1+3x^2

Does there exist 2 distinct prime numbers such that their product is a square number?

satela [25.4K]

Answer:

NO.

Step-by-step explanation:

If the 2 prime numbers are odd then the product cannot be a square number because the only factors are the original prime numbers. If one of the prime numbers is 2 then the product will be an even number , but again the only factors will be 2 and the other prime number.

So the answer is No.
