Make y the subject of the formula W= x squared - 2yz

AveGali [126]

Answer:

The formula $y = \frac{x^{2} }{2z} + \frac{W}{2z}$

Step-by-step explanation:

Explanation

Given W = x² - 2 y z

2 y z = x² + W

Dividing '2z' on both sides , we get

$\frac{2yz}{2z} = \frac{x^{2} + W}{2z}$

⇒ $y = \frac{x^{2} }{2z} + \frac{W}{2z}$
