Factor in this expression 6z ^ 4 - 4 + 9(y ^ 3 + 3)

 6z ^ 4-4 is a factor

Step-by-step explanation:

Given data

6z ^ 4 - 4 + 9(y ^ 3 + 3)

open bracket

6z ^ 4 - 4 + 9y ^ 3 + 27

collect like terms

6z ^ 4+9y^3 - 4 +27

6z ^ 4+9y^3 - 23

From the above expression  6z ^ 4-4

for question no. 3

solution : -

a(-3,-4) = (x1,y1)

b(-1,8) =(x2,y2)

slope =?

we have ,

: . slope (m) = y2-y1/x2-x

=8+4/-1+3

=12/2

= 6 (ans.)
