Question

how do I turn (4x-1) into (1-4x)

Answer 1

\[-(4x-1) =-(4x)-(-1)=-4x+1=1-4x\]
So basically (4x-1) = -(1-4x) and (1-4x) = -(4x-1)

Answer 2

So multiply by -1

Answer 3

Yes.

Answer 4

(4x-1) * -1 = -(4x-1) = -4x + 1 = 1 - 4x

Answer 5

Do I have to multiply a numerator too

Answer 6

I have 24x^4-8x^3+3/(4x-1)^2 And on wolfram it simplifies to 24x^4-8x^3+3/(1-4x)^2

Answer 7

Depends on the problem. But if you multiply a numerator by -1, you must distribute a -1 to the denominator as well.

Example:
\[\frac{(4x-1)}{1-4x}=\frac{-(1-4x)}{1-4x} = -1\]

Answer 8

\[ (4x-1)^2 = (4x-1)(4x-1)=-1(1-4x)*-1(1-4x)\]
\[=(-1)^2(1-4x)^2=(1-4x)^2\]
