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