All are True

a) 30a^6-24a^2=3à^2 (10a^4-8)

b) 24a^4+18=6 (4a^⁴+3)

c) 16a^5-20a^3=4a^3 (4a^2-5)

D) 12a^3+8a=4 (3a^3+2a)

Step-by-step explanation:

a) 30a^6-24a^2=3à^2 (10a^4-8)

since; 3à^2 (10a^4-8)

= 30a^6 - 24a^2

b) 24a^4+18=6 (4a^⁴+3)

Since; 6 (4a^⁴+3) opening the brackets

= 24a^4 + 18

c) 16a^5-20a^3=4a^3 (4a^2-5)

Since; 4a^3 (4a^2-5), opening the brackets we get

= 16a^5 - 20^3

D) 12a^3+8a=4 (3a^3+2a)

Since; 4 (3a^3+2a) , opening the bracket we get;

= 12a^3 + 8a
