Question

factorise 3(x+y)^2-8(x+y)+5​

Answer 1

let x + y be a

3a² - 8a + 5

= 3a² - 5a - 3a + 5

= a ( 3a -5 ) -1 (3a - 5 )

(a - 1 ) ( 3a - 5 ) Answer..

Answer 2

Answer:

Here's your answer

Let x+y be a

$3 {a}^{2} - 8a + 5 \\ \\ 3 {a}^{2} - 3a - 5a + 5 \\ \\ 3a(a - 1) - 5(a - 1) \\ \\ (a - 1)(3a - 5) \\ \\ = (x + y - 1)(3x + 3y - 5)$

Hope it helps ✌✌....
