Question

(x2 + 3x)2 – 5 (x2 + 3x) – y (x2 + 3x)+ 5y​

Answer 1

Step-by-step explanation:

(2x2+6x)+(-5x2-15x)+(-x2y-3xy)+5y

=-3x2-9x-x2y-3xy+5y

=x2(3-y)-3xy-9x+5y

Answer 2

Answer:

this is correct answer

Step-by-step explanation:

(x2+3x)2-5(x2+3x)-y(x2+3x)+5y

=(x2+3x)-y(x2+3x)-5(x2+3x)+5y

=(x2+3x )[(x2+3y)-y]-5[(x2+3x)-y]

=(x2+3x )(x2+3x-y)-5(x2+3x -y)

=(x2+3x-y)(x2+3x-5)

I hope it HELPS you
