Simplify
−2(j^2− k) − 6(j^2 + 3k )

-8j^2-16k

Step-by-step explanation:

First step:-2j^2-(-2)k=-2j^2+2k

Second step:

-6(j^2+3k) use the formula a(b+c)=ab + ac

a=-6 b=j^2 c=3k

-6j^2+(-6).3k

-6j^2-6.3k=-6j^2-18k because we multiplied 6x3=18

So we gather the whole equation And simplify

-2j^2+2k-6j^2-18k

-2j^2-6j^2 +2k-18k(add like terms)6+2=8

-8j^2+2k-18K (subtract Like terms 18-2=16)

And the answer will give -8j^2-16k

step- i d k and i d c : )

you: : 0

bye

i think it is 18
