Answer 2

Solution for (x+2)(x-5)-3x(1-2x) when x = -1

To solve the expression (x+2)(x-5)-3x(1-2x) when x = -1, we'll substitute x with -1 and simplify the expression.

Substitute x with -1: (x+2)(x-5)-3x(1-2x) = (-1+2)(-1-5)-3(-1)(1-2(-1))

Simplify the expression: = (1)(-6) - 3(-1)(1+2) = -6 + 3(-1)(3) = -6 + 3(-3) = -6 - 9 = -15

The value of the expression (x+2)(x-5)-3x(1-2x) when x = -1 is -15.
