Question

9x^2-9(a+b)x+(2a^2+5ab+2b^2)=0
​

Answer 1

Answer:

a+b-5,2a+2b+1

Step-by-step explanation:

that is answer ok

Answer 2

Answer:

This has two solutions:

x = (2a+b)/3 and

x = (a+2b)/3

Step-by-step explanation:

9x^2 - 9(a+b)x + (2a^2+5ab+2b^2) = 0

9x^2 - 9(a+b) + (2a+b) (a+2b) = 0

9x^2 - (9a + 9b) + (2a+b) (a+2b) = 0

[3x - (2a+b)] [3x - (a+2b)] = 0
