Answer:
Option B is correct.
Simplified form of \(-4x^2-5(x+3)+x^2\) is, \(-3x^2 -5x-15\)
Step-by-step explanation:
Given that: \(-4x^2-5(x+3)+x^2\) .....[1]
Like terms are those terms which have same variables to the same powers
Combine like terms in [1] we have;
\(-3x^2-5(x+3)\) .....[2]
Using distributive property: \(a\cdot (b+c) = a\cdot b+a\cdot c\)
Apply distributive property on [2] we have;
\(-3x^2 -5x-15\)
Therefore, the simplified form of \(-4x^2-5(x+3)+x^2\) is, \(-3x^2 -5x-15\)
