Question

Factorize using identity:

a) 27x³+ 125³

b) 9x²+6xy+y²

c) 27x³+y³+ z³-9xyz

anyone who will answer it,i will give him/her 10 points

​

Answer 1

Answer:

Explanation:

a)(3x+5)(9x²+25-15x)

b)(3x+y)²

=(3x+y)(3x+y)

c) (3x+y+z) [9x² +y² +z² —3xy —yz —3zx]

Answer 2

Answer:

27x³+125³

(3x+5)³

9x²+6xy +y²

product = 9x²ý²

sum = 6xy

(9x)² + (3x+3y) + y²

9x²+3x+3y +y²

3x(x+3)y(1+3)

(3x+y) (x+3)
