hwllo sir i want to know the best answer of this question from class 9th ncert book of exercise 2.5 of Polynomials chapter of math give me the best and simple way for solving this question in easy way Factorize the following using appropriate identities:(iii) x2–y2/100

Share

x

^{2}–y^{2}/100 = x^{2}–(y/10)^{2}Using identity, x

^{2}-y^{2 }= (x-y)(x+y)Here, x = x

y = y/10

x

^{2}–y^{2}/100 = x^{2}–(y/10)^{2}= (x–y/10)(x+y/10)
