Question

simplify.
$-3x^2 - 7x^2$

Explanation:

Step1: Identify like terms

The terms \(-3x^2\) and \(-7x^2\) are like terms (same variable part \(x^2\)).

Step2: Combine coefficients

To combine like terms, add their coefficients. The coefficient of \(-3x^2\) is \(-3\) and of \(-7x^2\) is \(-7\). So, \(-3 + (-7)=-10\).

Step3: Write the simplified term

Multiply the combined coefficient with the variable part \(x^2\), giving \(-10x^2\).

Answer:

\(-10x^2\)
