Question

Factorise (a2 + 9b2 - 6ab) - 4c2 ​

Answer 1

{(a)^2+(3b)^2-(2×a×3b)} -4c^2

(a - 3b)^2 - (2c)^2

(a - 3b - 2c) (a - 3b + 2c)

Answer 2

Answer:

$( {a}^{2} + 9 {b}^{2} - 6ab) - 4 {c}^{2} \\ ( {a})^{2} + (3 {b)}^{2} - 3 \times 2ab \: - 2 {c}^{2} \\ (a + 3b {)}^{2} - (2 {c})^{2} \\ (a + 3b - 2c)(a - 3b + c)$
