Question

W=-2, x = 3, y=0, z= -1/2 y²-w²/xz​

Answer 1

Answer:

$=\frac{8}{3}$

Step-by-step explanation:

If w = -2, x = 3, y = 2 and z = -1/2 then find the value

$\frac{y^{2}-w^{2} }{xz}$

Given:

• w = -2
• x = 3
• y = 0
• z = -1/2

Formulas:

• a²-b² = (a+b)(a-b)
• (-a)² = a²
• (-a) × (-b) = ab
• 1/(a/b) = b/a

To find:

$\frac{y^{2}-w^{2} }{xz}$

$\frac{0^{2}-(-2)^{2} }{3*\frac{-1}{2} }$

$\frac{0-4}{\frac{-3}{2} }$

$-4*-\frac{2}{3}$

$=\frac{8}{3}$
