Lutasin ang (x+y)^2-z^2/x^2-(y+z)^2

$$\frac { ( x + y ) ^ { 2 } - z ^ { 2 } } { x ^ { 2 } - ( y + z ) ^ { 2 } }$$

I-evaluate

$$\frac{x+y-z}{x-y-z}$$

Maiikling Hakbang sa Solution

I-factor ang mga expression na hindi pa na-factor.

$$\frac{\left(x+y+z\right)\left(x+y-z\right)}{\left(x+y+z\right)\left(x-y-z\right)}$$

I-cancel out ang x+y+z sa parehong numerator at denominator.

$$\frac{x+y-z}{x-y-z}$$
