Question

Factorise 3(x+y)square-5(x+y)+2

Answer 1

Answer:

{3(x+y) - 2} {x+y-1}

Step-by-step explanation:

Let (x+y) = z

Therefore, the equation becomes:

= 3z² - 5z + 2

= 3z² -3z -2z +2

= 3z(z-1) -2 (z-1)

= (3z-2) (z-1)

Now put z=x+y in the above equation:

= {3(x+y) -2}{x+y -1}

Hope I was able to help you.

Thanks for asking.
