Simplify the power of (x plus 1) multiplied by (2x minus 1) minus (x minus 3), where x equals minus 2

(x+1)(2x-1)-(x-3)²
=(2x²-x+2x-1)--(x²-6x+9)
=2x²+x-1-x²+6x-9
=x²+7x-10
=(-2)²+7×(-2)-10
=4-14-10
=-20

In the evaluation. X minus two-thirds x plus three minus x, where. X equals minus one

X-2 / 3x + X / (3-x) = 1 / 3x + X / (3-x) = (6x-x ^ 2) / (9-3X) to get - 7 / 12
