發問:
Factorize (10point) x^2 - (y-z) ^ 2
x^2-y^2≡(x+y)(x-y) x^2-(y-z)^2 ＝[x+(y-z)][x-(y-z)] ＝(x+y-z)(x-y+z)
其他解答:
x^2 - (y-z) ^ 2 Let x be a and (y-z) be b =a^2 - b^2 = (a+b)(a-b) = (x+y-z)(x-y+z)|||||Factorize the following: x^2 - (y-z) ^ 2 Formula: (x+y)(x-y) = x^2-y^2 Solution: = [x+(y-z)][x-(y-z)] = (x+y-z)(x-y+z)
