Question

value of
$(2 \sqrt{10} - 3 \sqrt{5} )2 \sqrt{2 \\ \\ }$
​

Answer 1

Answer:

Problem 1.4 Factor (a+2b−3c)3+(b+2c−3a)3+(c+2a−3b)3.

Solution Observe that (a+2b−3c)+(b+2c−3a)+(c+2a−3b)=0. Because x+y+z=0 implies x 3+y 3+z 3=3xyz, we obtain

(a+2b−3c)3+(b+2c−3a)3+(c+2a−3b)3=3(a+2b−3c)(b+2c−3a)(c+2a−3b).
