Answer:
Option 2 and 3
Step-by-step explanation:
We know that as per distributive law, we have [tex]a(b+c)=ab+ac[/tex].
Option 1.
[tex]-5x^3(3x^3+2)=-15x^6-10x^3\neq -15x^9-10x^3[/tex]
So, option 1 is not correct.
Option 2.
[tex]-2c^6(5c^3+6)=-10c^9-12c^6[/tex]
So, option 2 is correct.
Option 3.
[tex]-3y^5(2y^3+3)=-6y^8-9y^5[/tex]
So, option 3 is correct.
Option 4.
[tex]-4b^4(5b^2+6)=-20b^6-24b^4\neq -20b^8-24b^3[/tex]
So, option 4 is not correct.
