(w+1)(w-1)=w(w-4)

(w + 1) (w - 1) = w (w - 4)

w = \frac{1}{4}

Solution steps

(w + 1) (w - 1) = w (w - 4)

Expand

(w + 1) (w - 1) : w^{2} - 1

Expand

w (w - 4) : w^{2} - 4 w

w^{2} - 1 = w^{2} - 4 w

Move

1

to the right side

w^{2} = w^{2} - 4 w + 1

Subtract

w^{2} - 4 w

from both sides

w^{2} - (w^{2} - 4 w) = w^{2} - 4 w + 1 - (w^{2} - 4 w)

Simplify

4 w = 1

Divide both sides by

4

w = \frac{1}{4}

- \frac{π}{2} + 2 π

x^{3} y - 9 x y^{3}

\frac{11 !}{7 ! 4 !}

2 x + 3 < 9

5 - 3 (2 + x) = - 4

What is the answer to (w+1)(w-1)=w(w-4) ?
