Question

Simplify the expressions
-7x^4 - 4 + 10x^2

-3(x-2)

Answer 1

Let's simplify each expression step by step.

1. **For the expression \(-7x^4 - 4 + 10x^2\)**:
This expression is already simplified in terms of like terms. We can rearrange the terms in standard polynomial form:

\[
-7x^4 + 10x^2 - 4
\]

So, the simplified form of the first expression is:
\[
-7x^4 + 10x^2 - 4
\]

2. **For the expression \(-3(x-2)\)**:
We can distribute \(-3\) across the parentheses:

\[
-3 \cdot x + (-3) \cdot (-2) = -3x + 6
\]

So, the simplified form of the second expression is:
\[
-3x + 6
\]

Putting it all together:
- The simplified form of \(-7x^4 - 4 + 10x^2\) is \(-7x^4 + 10x^2 - 4\).
- The simplified form of \(-3(x-2)\) is \(-3x + 6\).
