What is 4x2+12x+84x2

Question

?

Answer 1

To simplify the expression \( 4x^2 + 12x + 84x^2 \), you can combine like terms.

First, combine the \( x^2 \) terms:

\[ 4x^2 + 84x^2 = (4 + 84)x^2 = 88x^2 \]

Now, rewrite the expression with the combined terms:

\[ 88x^2 + 12x \]

So, the simplified expression is:

\[ 88x^2 + 12x \]
