Question

1 - 2a – 2b – 3 (a + b)2​

Answer 1

Answer:

a+b=1/8

Step-by-step explanation:

1-2(a+b)-3(a+b)2

1-2(a+b)-6(a+b)

1-8(a+b)

1=8(a+b)

1/8=a+b

Answer 2

Answer:

Solve:-1-2(a+b)-3(a+b)2a+b=X

1-2x-3xsquare=-3xsquare-2x+1

-3xsquare-3x+X+1

-3x+1)+1(X+1)

(x+1)(1-3x)

(a+b+1)(3-3(a+b))

(a+b+1)(1-3a-3b)

Step-by-step explanation:

answer:-(a+b+1)(1-3a-3b)
