Answer:
[tex]=\frac{8}{3}[/tex]
Step-by-step explanation:
If w = -2, x = 3, y = 2 and z = -1/2 then find the value
[tex]\frac{y^{2}-w^{2} }{xz}[/tex]
Given:
Formulas:
- a²-b² = (a+b)(a-b)
- (-a)² = a²
- (-a) × (-b) = ab
- 1/(a/b) = b/a
To find:
[tex]\frac{y^{2}-w^{2} }{xz}\\[/tex]
[tex]\frac{0^{2}-(-2)^{2} }{3*\frac{-1}{2} }[/tex]
[tex]\frac{0-4}{\frac{-3}{2} }[/tex]
[tex]-4*-\frac{2}{3}[/tex]
[tex]=\frac{8}{3}[/tex]
