-3а^4+48=-3(а^4-16)=-3(а^2-4)(а^2+4)=-3(а-2)(а+2)(а^2+4)

Answer 2

I can help you with your math problem. To simplify the expression -3a^4+48, you need to factor out the common term -3 from both terms. The result is:

$$-3a^4+48=-3(a^4-16)$$

Then, you can use the difference of squares formula to factor the expression inside the parentheses. The formula is:

$$a^2-b^2=(a+b)(a-b)$$

In this case, a^4 is a perfect square of a^2, and 16 is a perfect square of 4. So, you can write:

$$a^4-16=(a^2)^2-(4)^2=(a^2+4)(a^2-4)$$

Substituting this back into the original expression, you get:

$$-3(a^4-16)=-3(a^2+4)(a^2-4)$$

This is the final answer. You can check it by expanding the factors and simplifying. You should get the same expression as the original one.
