Question

W=x^2-2yx make y the subject of the formula

Answer 1

Answer:

$y=\dfrac{x^2-w}{2x}$

Step-by-step explanation:

The given equation is :

w=x²-2yx

We need to find the value of y.

Subtract x² from both sides.

w-x²=x²-2yx-x²

w-x² = -2yx

Dividing both sides by -2x

$\dfrac{w-x^2}{-2x}=\dfrac{-2yx}{-2x}\\\\y=\dfrac{w-x^2}{-2x}\\\\y=\dfrac{x^2-w}{2x}$

So, the value of y is equal to $\dfrac{x^2-w}{2x}$.
