Question

Simplify.

−4x2−5(x+3)+x2

−4x2−5x−15

−3x2−5x−15

−9x2−15

−23x

Answer 1

−4x2−5(x+3)+x2= -8-5x-15+2x=-3x-23
−4x2−5x−15=-8x-5x-15=-13x-15
−3x2−5x−15=-6x-5x-15=-11x-15
−9x2−15=-18x-15
i simplified assuming it's an "x"-sign not multiplication
hope this helps

Answer 2

Option 2nd is correct

`-3x^2-5x-15`

Explanation:

The distributive property says that:

`a \cdot (b+c) = a\cdot b+ a\cdot c`

Given the equation:

`-4x^2-5(x+3)+x^2`

Combine like terms;

`-3x^2-5(x+3)`

Apply the distributive property we have;

`-3x^2-5x-15`

therefore, the simplified form for the given equation is:

`-3x^2-5x-15`
