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

sammy [17]

Answer:

$3x^2+3y^2+6xy-5x-5y+2$

Step-by-step explanation:

$3(x+y)^2 -5(x+y) + 2$

$\mathrm{Expand}\:-5\left(x+y\right)+2$

$-5x-5y+2$

$\mathrm{Simplify}\:3\left(x+y\right)^2$

$3\left(x^2+2xy+y^2\right)$

$3x^2+3\times \:2xy+3y^2$

$3x^2+6xy+3y^2$

$=3x^2+3y^2+6xy-5x-5y+2$
