No. Let x = 0 -2(0) + 3 = 3 2(0)- 3 = - 3 Do you see that the answers are different?

I had been taught not to leave a negative answer, so -2x + 3 would be 2x - 3. Was I taught wrong?

No.

-2x+3=2x-3 => 4x=6 => x=3/2 Ans. if & only if x=3/2.

In a word_______ NO !!!! - 2x + 3 = - ( 2x - 3 )

-2x+3 is not the same thing as 2x-3 It is the negative of the first expression, as you said. -2x+3 = 0 is the same as 2x-3 = 0 Don't confuse a polynomial expression with an equation.

Test them for x=0.

What if they don't equal 0? Let x = 1. -2(1) + 3 = 1 but 2(1) - 3 = -1 Therefore, the expressions are not equal.

No. -2x + 3 =/= 2x - 3 for all real x, and you answered your own question in so doing. -2x + 3 = -1(2x - 3), and dividing both sides by 2x - 3 means -1 = 1. False statement for all x except if x = 3/2.

if they were the same, then they would be equal for any value of x, but they are not equal at x=0

-2x + 3 = (2x - 3) × (-1) If -2x + 3 = 0, then (2x - 3) × (-1) = 0 2x - 3 = 0 Therefore, you can simplify -2x + 3 = 0 as 2x - 3 = 0. However, it is INCORRECT to simplified -2x + 3 as 2x - 3.
