Answer 2

To find the value of the expression 2x-4(3x-2)x(12x-2) when x=-2 and x=5, we substitute the given values into the expression and simplify.

1) Let's first substitute x=-2:

2(-2) - 4(3(-2)-2)(-2)(12(-2)-2) = -4 - 4(-6-2)(-2)(-24-2) = -4 - 4(-8)(-2)(-26) = -4 - 4(16)(-2)(-26) = -4 - 4(-32)(-26) = -4 - 4(832) = -4 - 3328 = -3332

So, when x=-2, the value of the expression is -3332.

2) Now let's substitute x=5:

2(5) - 4(3(5)-2)(5)(12(5)-2) = 10 - 4(15-2)(5)(60-2) = 10 - 4(13)(5)(58) = 10 - 4(65)(58) = 10 - 4(3770) = 10 - 15080 = -15070

So, when x=5, the value of the expression is -15070.
