\(\huge\color{purple}{(−2x^2)}\) \(\huge\color{green}({−5x^2+4x^3)}\)

Answer 2

$$\Huge a(b+c) = ab +ac$$

Answer 3

\(\huge\color{purple}{(−2x^2)(-5x^2)}\) \(\huge\color{red}{+}\)\(\huge\color{green}{(-2x^2)(4x^3)}\)

Answer 4

I multiply- 2 and -5 and do the same for 2 and 4 then add...is in right or wrong

Answer 5

You are half right, you do multiply -2 and -5 and do the same for -2 and 4 but then you can not add them because of the variable x that they multiply.
