How do you simplify #3x (x -1) - 4 (x^2 - x)#?

Answer 1

Abigail Allen

x(1-x)

In order to simplify this equation , you need to expand it .

3x(x-1) - 4( x^2 - x) = 3x^2 - 3x - ( 4x^2 - 4x )

To simplify (3x(x - 1) - 4(x^2 - x)), we first distribute the terms within the parentheses:

(3x^2 - 3x - 4x^2 + 4x)

Next, we combine like terms:

(3x^2 - 4x^2 - 3x + 4x)

Now, we can simplify further by combining like terms:

(-x^2 + x)

So, (3x(x - 1) - 4(x^2 - x)) simplifies to (-x^2 + x).
