Question

please say the answer anyone.... i will mark u as brain list

Answer 1

9 x^2-9(a+b)x+(2a^2+5ab+2b^2)=0
9x^2-3(3a+3b)x+(2a^2+4ab+1ab+2b^2)=0
9x^2-3[(2a+b)+(a+2b)]x+[2a(a+2b)+b(a+2b)]=0
9x^2-3(2a+b)x-3(a+2b)x+[(a+2b)(2a+b)]=0
3x[3x-(a+2b)]-3(2a+b)x+[(a+2b)(2a+b)]=0
3x[3x-(a+2b)]-(2a+b)[3x-(2a+b)]=0
[3x-(a+2b)] [3x-(2a+b)]=0
3x-(a+2b)=0
3x=a+2b
x=(a+2b)/3
OR
3x-(2a+b)=0
3x=2a+b
x=(2a+b)/3
