Question

Simplify and find the value of the expression 6x²y - 3(2x²y - 4y) when:
a) y=-4
b) y = 0
c) y = 6
d) y = 1 6

first simplify equation and subtute with the options ​

Answer 1

Step-by-step explanation:

6x²y - 3(2x²y - 4y) = 6x²y - 6x²y +12y

= 12y

Now,

a) y = -4

12y = 12*(-4)

= (-48)

b) y = 0

12y = 0

c) y = 6

12y = 72

d) y = 16

12y = 192
