Question

a²-3 ac + a -3 b - a - b² -2ab if value x = 0 , b = -1

Answer 1

Given expression is $a^3-3ac+a-3b-a-b^2-2ab$.

Now we just need to plug given values x = 0 , b = -1 to simplify that equation.

$a^2-3ac+a-3b-a-b^2-2ab$

plug value of b=-1 as other values are not given.

$=a^2-3ac+a-3(-1)-a-(-1)^2-2a(-1)$

$=a^2-3ac+a+3-a-1+2a$

Combine like terms

$=a^2-3ac+2+2a$

Hence final answer is $a^2-3ac+2+2a$
