Answer 1

Answer:

9x2 - 9(a + b) x + (2a2+ 5ba + 2b2) = 0

9x2 - 9(a + b)x + (2a + b) (a + 2b) = 0

9x2 - 3(2a + b)x - 3 (a + 2b)x + (2a + b) (a + 2b) = 0

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

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

x =

Step-by-step explanation:

9x2 - 9(a + b) x + (2a2+ 5ba + 2b2) = 0

9x2 - 9(a + b)x + (2a + b) (a + 2b) = 0

9x2 - 3(2a + b)x - 3 (a + 2b)x + (2a + b) (a + 2b) = 0

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

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

x =
